The housing consists of a closed insulating case. It is designed to hold electric wiring either on the surface of a wall or buried in the plaster. The lateral walls (21a, 23a) of the case consist of at least two sandwich-like parallel walls (34, 35), and there is a slot (36) between them which is open towards the edge (46) of the case. The extension (37) of a case border (38) can be inserted into the slot, in which it can move in the height direction and it is fixed.
