In this device, the wall holder has an angular shape and the covering cap is clamped on threaded pins which are arranged inside said covering cap and project from the insides of both limbs of the wall holder. For the purpose of securing a positionally correct arrangement of the cap relative to the wall holder, a cap screw (9) which is directed at right angles to the first, wall-side limb (4) is mounted so that it can be screwed in said first wall-side limb. Furthermore, an intermediate wall (10), which is parallel to the first wall holder limb (4), is provided inside the cap (1) with a slot (11) which is parallel to the first wall holder limb (4), is as wide as the shank of the screw, is open at the bottom and is penetrated by the screw shank (16), the screw head (17) being supported on the edge parts of the slot, and the insertion opening of the cap (1), corresponding to the threaded pin (13) of the second wall holder limb (6), is constructed as an elongate hole in alignment with the cap screw (9). <IMAGE>
