Detachable plug connection

Detachable plug connection (1) comprising a connecting element (2) which is connected to a sleeve-like receiving part (3), an interior of which is intended for introduction of a tubular plug-in part (4) which carries a circumferential retaining rib (5) on an outer circumference thereof, and having a securing element (6) which is comprised of hard-elastic material and has inwardly directed retaining edges (7), which can spring out elastically, for engaging behind the retaining rib (5) after the plug-in part (4) has been pushed in, said retaining edges (7) being connected together via resilient webs (8, 9) which converge in a V shape, and which can spring out by application of pressure to converged web end regions of the resilient webs (8, 9), such that the retaining edges (7) disengage from the retaining rib (5), the connecting element (2) and the securing element (6) are connected integrally together to form a moulding (10) produced from hard-elastic material, and the connecting element (2) and the securing element (6) are connected together via deflectable resilient bars (11), in a course or extension of which at least one of the retaining edges (7) is provided.
