The retaining element (,) can be pushed in from the outside in an opening (,) of the housing wall (,) to release the plug-in element (,). The receiving space (,) consists of three stepped sections. The housing (,) is embodied as a two-part structure. In order to move the opening (,) for pushing in and releasing the retaining element (,) into a better position, if necessary, when only limited space is available. The head part (,) can be connected to the base body (,) in an axial direction and has a centering bush (,) at the plug-in side.
