ABSTRACT:
A releasable plug-in connector having a tubular plug-in part with a peripheral retaining rib, a housing having a cylindrical receiving space having a central axis for receiving the plug-in part and at least one opening in a side wall of the housing communicating with said receiving space and a separate retaining ring of a hard, resilient plastic material and having radially inwardly directed, elastically sprung retaining edges for engaging behind the retaining rib of the plug-in part after the plug-in part has been inserted into the receiving space of the housing to lock the plug-in part in the housing. The retaining ring is insertable through the opening in the housing and into the receiving space so that the ring is retained against axial movement by the housing while the retaining edges are concentric with the axis of the receiving space, the retaining edges being able to be pushed apart in a radial, direction to release the plug-in part by pressing in on the ring through the opening. The improvement comprises a protective cap that can be installed over the outer side of the housing, the protective cap having a protective ring that extends around the housing and covers, at least partially, the opening in the side wall of the housing in a protective position and spring means for holding the ring in the position while permitting the ring to be pushed aside to expose the opening and permit pressing in of the retaining ring to release the plug-in part.
