DETACHABLE PLUG CONNECTION

WIPO Patent Application WO/2013/104533

A3

The invention relates to a detachable plug connection (1) comprising a tubular insert piece (2) which supports at least one retaining projection (3) on its external circumference, a sleeve-shaped receiving piece (4), the interior of which is used to insert the tubular insert piece (2), and a connection element (5) which is connected to the receiving piece (4) on which at least one retaining edge (6, 7), which is directed inwards and can be bent or pivoted upwards, engages behind the retaining projection (3) after pushing in the insert piece (2). According to the invention, said connection also comprises a sleeve-shaped securing element (8) which surrounds the connection element (5) in a sliding manner such that the securing element (8) can be displaced between a release position, in which the axial sliding movement of the securing element (8) can be transformed into an opening movement of the retaining edge(s) (6, 7) oriented transversally thereto, and a securing position, in which the securing element (8) surrounds the connection element (5) such that the connection element (5) cannot be bent upwards in the region of the retaining edge(s) (6, 7) and such that the connection element (5) projects at least in parts above the securing element (8), in an intermediate or coupling position of the securing element (8) in such a manner that the retaining edge(s) (6, 7) can be bent upwards when the retaining projection (3) on the insert piece (2) is pushed in.
