ABSTRACT:
The detachable plug coupling operative to connect fluid lines, particularly fuel lines of motor vehicles. The plug coupling includes a tubular insertion part with an encircling retaining rib and a coupling housing having a cylindrical accommodating space for the insertion part. The plug coupling also has an enlarged head part with a separate retaining element, having elastically opening retaining edges. The retaining edges are radially directed into the accommodating space and engage behind the retaining rib after the insertion part has been pushed in. In order to ensure that the retaining rib is correctly snapped in behind the retaining edges after the insertion part has been inserted, an additional locking element is provided, which is guided in a transversally displaceable manner on the housing head between an opening position and a closing position.
