Abstract
A connector having a plug part insertable in a sealing and locking manner into a receiver opening of a socket part. An annular retaining element is preassembled into a ring groove of one of the connector parts, prior to insertion. The retaining element is deformable in a radially elastic manner during the insertion process so that the sealing element is pressed into the ring groove, and the retaining element then deforms in an elastic manner into a locking position to engage a ring groove of the other connector part. The retaining element corresponds at least approximately in longitudinal and transverse cross section to the longitudinal and transverse cross sections of the first-mentioned ring groove, at least over two diametrically-opposed regions of the circumference of that ring groove.
