2. The Prior Art: In many fields of mechanical engineering there is the problem to interconnect two parts. An important case is the connection between a lever and a Bowden cable, for example when the movements of a shift lever are to be transmitted via a Bow- den cable to the gear box of a vehicle or when a parking brake is to be operated by means of a braking lever via two braking cables. Thus, such a connection is in particular used in the automotive field, but also in construction machines or sport equipment a plurality of connections between separate components of a machine or the device are needed.

Such a device has to meet different requirements. On the one hand it should be reliable and stable so that the parts do not become unintentionally disconnected during their use (operation of a vehicle, movement of a construction machine, etc.) On the other hand, the connection should for cost reasons be designed such that the parts can during assembly easily and without excessive force be manually assembled. Connections with screws or the like are therefore excluded from the beginning.

In the prior art constructions are well-known, where the maximum mechanical loading on the connection exceeds the necessary force during assembly many times. These arrangements consist typically of a sphere-like head attached to the first part which is snapped into a dome shaped receptacle attached to the second

part, whereby the sides of the dome shaped receptacle are bent. In order to provide a lasting latching of this connection, the dome shaped receptacle moves on a slide or the like together with the sphere-like head into an opening or recess of the sec- ond part whose walls avoid a bending of the sides of the dome shaped receptacle.

When the slide is latched at the end of the sliding motion, the simple movement of the sphere-like head in the direction of the dome shaped receptacle not only pro- vided the actual connection between the two parts but also the automatic latching of the connection, which is therefore capable to resist mechanical loading ex- ceeding many times over the force required for assembly.

In many cases, however, the connection also has to be easily releasable. In case of the mentioned examples from the automotive field it is for example during repairs necessary to replace the Bowden cables and to separate them from the shift lever or braking lever. The connections used in the prior art are either (without destruc- tion) not releasable at all or they require complicated special tools in order to re- lease the slide or the like from its latched position so that the dome shaped recep- tacle can be moved back into its starting position and the sphere-like head can be removed therefrom.

A further disadvantage of connections of the described type is the fact that the stable connection between the sphere-like head and the dome shaped receptacle is directly transmitting vibrations from one part to the other part. This is in many cases a disadvantage, in particular for the above mentioned connection between a shift lever and a Bowden cable, since the vibrations transmitted from the motor on the cable can thus be felt in the shift lever which renders precise shifting move- ments more difficult.

It is therefore the problem of the present invention to provide a simple and inex- pensive connection between two parts which provides on the one hand a high me-

chanical stability with an easy assembly but which can also easily manually be released.

According to a further aspect of the present invention, the connection is to damp the transmission of vibrations between the two parts.

3. Summary of the Invention: The invention relates to a connecting element for the releasable connection of a first part to a second part, in particular a cable to a lever, wherein the connecting element comprises a housing rigidly attached to the first part, an engaging element attached to the second part and a slide with a receiving element complementary shaped to the engaging element for the releasable connection of the engaging ele- ment with the receiving element, wherein the slide can slide inside the housing from a first position into a second position for latching the releasable connection between the engaging element and the receiving element. The connecting element further comprises at least one latching means for fixing the slide in the second position and at least one releasing means which serves for manually acting onto the at least one latching means to release the slide from the second position for unlatching the releasable connection between the engaging element and the re- ceiving element.

By the at least one releasing means, which is integrally connected with the con- necting element, the slide can with a simple movement of the hand be released from its latched position, in order to separate the two parts from each other. Spe- cial tools or special technical skills are not necessary. Thus, it is for example in case of the use in the automotive field also for a non-skilled person possible to perform repairs which need a disassembly of the connected parts. However, the high mechanical stability of the connection remains unaffected.

Preferably, two snapping hooks are provided as the at least one latching means.

The at least one releasing means is preferably provided as extensions of the two snapping hooks extending over the edge of the housing. In this preferred embodi- ment of the invention the slide is released from its latched position simply by manually pressing the extensions together. Since the force for pressing attacks at the end of the extensions, an easy release is due to the lever principle also possible in case of a stable latching.

According to a particularly preferred embodiment, the slide slides along a bushing extending through the housing. This bushing allows by a suitable material selec- tion an optimization of the sliding properties of the slide and facilitates thus the assembly of the two parts. Preferably, the bushing is apart from one or more slits for the release means closed by a cover on the side opposite to the receiving ele- ment.

A damping element for damping the transmission of vibrations between the two parts is preferably provided inside the housing. Preferably, the damping element is arranged between the bushing and the housing. Thus, the vibrational damping does not affect the stability of the connection between the engaging element and the slide. Preferably, the bushing has lateral projections or edges coacting with recesses of the damping element for its fixing.

Further advantageous developments of the present invention are the subject matter of the depending claims.

Short description of the drawing: In the following detailed description presently preferred embodiments of the pres- ent invention are described with reference to the figures, which show: Figure 1: A cross-section through a first preferred embodiment of the con- necting element according to the invention immediately before the two parts are assembled; Figure 2: the same cross-section as in Figure 1 through the first preferred embodiment in the latched state; Figure 3: a top view of the preferred embodiment of the Figures 1 and 2; Figure 4: a cross-section through a further preferred embodiment without vibrational damping.

5. Detailed description of the invention With reference to Figure 1 the connecting element 1 comprises a housing 10, which is mounted to a first part 20. For connecting, an engaging element 30, which is mounted to a second part 40, is inserted into the housing 10 (see the lower vertical arrow in Figure 1). The two parts 20 and 40, of which in Figure 1 only the corresponding ends to be connected are schematically shown, can be any arbitrary mechanical elements, for example a bar or the end of a Bowden cable etc. In the preferred embodiment of the connecting element 1, shown in Figure 1, an essentially rectangular connection is produced. With a correspondingly modi- fied housing 10 also a straight interconnection is possible, as well as any other

angle. This is without any importance for the mechanism of the connecting ele- ment 1 according to the invention described in the following.

The preferably sphere or egg shaped engaging element 30 snaps under a move- ment in the direction of the arrow (cf. Figure 1) into the preferably dome shaped receiving element 51, arranged at the lower end of a slide 50. The sides of the receiving element 51 are preferably provided with openings 52 which allow a lat- eral bending of the receiving element 51 to facilitate the connecting and releasing of the engaging element 30 with or from the receiving element 51. The slide 50 is preferably slideably arranged within a bushing 60 and preferably preliminary fixed by lateral snapping hooks 53 which engage corresponding recesses 61 of the bushing 60. Under a further movement of the engaging element in the direction of the arrow, the complete slide 50 slides from its starting position upwards inside the bushing 60 (cf. upper vertical arrow in Figure 1), until an intermediate support 55 of the slide 50 contacts the lower side of a cover 70 (cf. Figure 2) which closes the housing on its upper side. Also other limitations for the sliding movement are possible, for example a stopper inside the bushing 60.

The preferred cover 70 protects the connecting mechanism against the accumula- tion of dirt and against damages. Furthermore, a holding and/or support surface 71 is provided on the upper side of the cover 70 for supporting the complete con- necting element 1 when the engaging element 30 is being inserted (cf. the indi- cated finger in Figure 1). In the preferred embodiment shown in Figures 1 to 3, the cover 70 is clipped onto the housing 10. Other ways of mounting are also pos- sible.

In the above position the snapping hooks 53 engage preferably the edge of the bushing 60 (cf. Figure 2) and thus fix the slide 50 against an axial movement in the direction of the downwards pointing arrow in Figure 2. Conceivable is also an

embodiment, where the snapping hooks 53 engage additional upper recesses (not shown) of a correspondingly elongated bushing 60.

When the slide 50 slides upwards, the sides of the receiving element 51 are auto- matically compressed by the bushing 60 so that the sphere-like or egg-like en- gaging element 30 is rigidly fixed within the receiving element 51. As a result, the upward movement of the connector 51 provides a connection between the first part 20 and the second part 50 which is capable to resist high mechanical loading.

As can be seen from Figure 2, preferably two releasing means 55 are provided for releasing the connection of the two parts 20,40 which are preferably provided as extensions of the two snapping hooks 53. When the slide is in the upper latched position, these two extensions 55 extend preferably through an opening 72 (cf.

Figure 3) in the cover 70 over the edge of the housing 10. Thus, it is by means of a simple pressing of the two extensions 55 (cf. horizontal arrows in Figures 2 and 3) possible to release the slide 50 from its latched position, so that it can slide downwards with a downwardly directed pulling on the first part 20 (cf. vertical arrow in Figure 2) and the dome shaped receiving element 51 can release the en- gaging element 30. The connecting element 1 is then once again in the starting position shown in Figure 1.

In order to allow an easy manual release of the slide 50 from its latched position even with very stiff snapping hooks 53, the releasing means 55 might be longer than shown in Figures 1 and 2. The stiffness of the snapping hooks 53, which is essential for the maximum mechanical loading, of the connection is determined by the flexibility and material thickness of the sidewalls of the slide 50.

Further to the above discussed embodiment, where the releasing means 55 are provided as extensions of the snapping hooks 53 it is also possible to separately provide them on the housing 10 and to have them act onto the snapping hooks 53 by a rotational or a sliding movement etc. to release the slide 50 from its latched position.

In the embodiment shown in Figures 1 to 3 of the connecting element 1 according to the invention, vibrations are damped additionally to the already described func- tions. To this end, a flexible damping element is preferably arranged between the bushing 60 in which the slide 50 slides and the housing 10. Vibrations of the housing 10 are therefore only to a limited extent transmitted to the bushing 60 and thus to the engaging element 30 on which the second part 40 is attached.

Preferably, the damping element 80 is arranged between a lower projecting edge 11 of the housing 10 and the already above mentioned cover 17 at the upper edge of the housing 10. Thus, a direct mechanical contact between the housing 10 and the bushing 60 is effectively avoided. For a fixing of the bushing 60 relative to the damping element 80 it comprises on the upper and the lower side lateral projec- tions or edges 62 engaging corresponding recesses 81 of the damping element 80.

Figure 4 shows a simplified embodiment of the present invention without a vibra- tional damping. In this case the slide 50 slides directly along an opening inside the housing 10. The recesses 61 for the preliminary fixing of the slide 50 in the first position are as well as additional recesses 12 for the upper position directly pro- vided in the housing 10. Further, the cover 70 is in this embodiment preferably an integral part of the housing 10 (cf. the hatching in Figure 4).

The described connecting element is preferably made of plastic materials or met- als. Metals have a greater stability, whereas plastic materials, as for example Polyamide, are less expensive to produce, for example with injection molding. For the damping element 80 preferably typical Elastomers are used. For the selection of the materials for the slide 50 and the bushing 60 or the housing 10, respec- tively, it should be taken care that good sliding properties are achieved in order to provide an easy connecting of the two parts.
