Abstract

The housing consists of an upper part which comprises three separate cover caps (3, 8), the two lateral cover caps (8) being held by one lock each. The lock consists in each case of two lateral holding channels (24) which have a perpendicularly running groove (23) on the central cover cap, into which groove a perpendicular rib (22) engages on the inside of the longitudinal side wall (14) of the lateral cover cap (8). In addition, a central holding tongue (25) is attached to the top area (10) of the lateral cover cap (8), in the horizontal groove (26) of which central holding tongue a rib (27) engages on the outside of the narrow side wall (21) of the central cover cap (3). <IMAGE>
