ABSTRACT:
A protective packing element bears at its end 5 which is to be fixed on a wall opening a coupling piece which can be locked therein. The coupling piece is equipped with tongue-like locking elements and can be plugged onto a plug which itself can be plugged, for example, into an electrical plug-in connector located behind the wall opening. The locking elements have assigned to them deflection faces on the outer circumference of the plug. The plug and packing element end or coupling piece are inserted together into the wall opening. The locking elements of the coupling piece engage behind the wall opening in the course of insertion of the plug and are spread apart by the deflection faces during the further insertion of the plug. The locking elements eventually overrun the deflection faces and are secured in a spread-apart position.
