BACKGROUND OF THE INVENTION The procedure of taking unlawful possession of bags is commonly achieved by force.

The technique is typically referred to : bag snatching, bag grabbing, cutting of the strap etc. Bag encroachment is achieved by gaining unauthorized access to the bag. This can be implemented by but not limited to: ripping, tearing, pounding and cutting of the bags walls, bottom, top, locking and seal devices, strap with the help of tools i. e. knifes, sharp and blunt instruments. This anti grab bag device is designed as a deterrent against this type of crime scenario by installation of an electronic alarm, type alarm of the sort of personal attack alarm, an elastic tripe wire, a security locking system and an armored netting system (wire meshing). The bag is the object in which one carry valuable belongings and is by that theft exposed. Therefor the general needs of carrying a security bag has a grate apprehends when examining the increasing statistic of crime.

FIELD OF THE TECHNICAL INVENTION The problems mentioned above has been notified earlier and various security arrangements for bags are rendering in patents. It is known through for instance U. S Pat. No 5,764,134 one has loosely placed a personal attack alarm with both light- and signal alarm. This reference is different from the present invention by its lack of protection against cutting of the walls of bag and even with the lack of alarm function activated when tearing the strap. Another approach is found in U. S. Pat. No 3,701,140 and U. S. Pat. No 5,920,260. These references are not filling the function for the security combination of anti grab, cutting of the strap and anti encroachment device by its lack of elastic wire running inside of the strap, protection of the walls together with lack of protection encroachment in bag. In reference U. S. Pat. No 4,885,570 the electricity is conducted with help of a wire running inside the strap to different alarm sensors which activates when snatching and cutting of the strap as the electric conducting wire is switched of and then activate the alarm. This wire is different in both appearance as in function by another alarm construction. Trying to reach protection for attack on the walls, several electricity wires are placed inside of the wall forming a zigzag figure.

SUMMARY OF THE INVENTION The purpose of this invention is to solve these problems according to the following : When bag snatching, the owner act by holding hard in the strap which together with the

elastic wire running along the strap-which spiral construction is distinguish in comparison with an inelastic wire, as the meaning of an elastic wire is that you can adjust the effect on the wire which affect the responds of the alarm when stretching, together with that the alarm is not affected by the weight of bag or its contains, when it is exposed for pressure-which with its connection to the alarm-pin forming the activation device then will be pulled out from the body of the alarm and activates the siren in the alarm. This very embarrassing siren will result in a need for the criminal to get rid of the bag. The siren will not stop until the metal pin is placed back in the body of the alarm. To prevent for the criminal to make this action a lock is connected to clasp attached in the strap and clasp attached in the seal device, particularly a zip, resulting in a prevention to open the locking device. Further prevention for pounding into the bag is an armored netting system, particularly wire meshing, bedded in the bags exterior walls. The elastic wire running inside the strap is so strong constructed as for example an instrument of normal capacity is not capable to cut off the wire.

BRIEF DESCRIPTION OF THE DRAWINGS Preferred embodiments of the present invention are illustrated in the drawings, wherein: FIG. I. is a cross section view of the bag and its safety device.

FIG. 2. is a perspective view of the alarm and its external activation device with a view over the construction for the holder of the alarm inside the bag.

FIG 3. is a perspective view on the attachment of the lock through clasp in strap and clasp in the seal device.

FIG. 4. is a perspective view on the attachment of elastic wire running along the strap to the activation device at the alarm by an on and off connectable fastening.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1, Illustrates a cross section view of present invention where the elastic wire (1) running along the whole length of the strap (15) ends with a clasp (2) in which a fastening (3) is fasted. This fastening can be opened and closed for connection to or from the activation device on the alarm (4). The activation device is connected to the alarm body (4, 5). The wire is on the opposite side attached with a fastening (6) in the wall of the bag. All the walls of bag are furnished with a strong net (12).

FIG. 2. Illustrates the back surface of the alarm provided a clip to be attached inside the bag. The clip is furnished with velcro closing (11) meeting velcro closing fixed at the wall inside the bag. The attachment is further reinforced by the clip tread on a holder (10) placed on the wall inside the bag. The position of the alarm can therefore not be displaced when snatched. The alarm can easily be detached when changing the battery. The activation device (4) is placed at the top of the alarm. The battery operate pitched 120 dbl. sound for reaching desired effect.

FIG. 3. Illustrates the inside of the strap at angle meeting the seal device (13).

The fastening (14) of the lock (8) is running through clasp (7) attached in the seal device and clasp (9) attached to the holder at the inside of the strap (15). By this an obstacle is achieved to open the seal device (13) and by that, preventing for the criminal to 5 inactivate the alarm (5) and its siren, FIG. 4. Illustrates the elastic wire (1) at its end attached clasp (2) which is connected with an on and offconnectable fastening (3) which then are connected with the activation device (4) who in its holder are connected to the alarm (5).
