ABSTRACT:
A device for mounting a cover to a support member is disclosed. In the exemplary embodiment the cover has a generally planar top surface and supports two side pieces protruding, in the same direction, from the top surface at approximately right angles thereto. A latching device is supported by each side piece. Each latching device comprises a plurality of prongs and is supported by the side piece such that the area of support is more remote from the top surface than are the free ends of the prongs. The prongs are biased out of the plane of the side piece. At least two recesses, one for each latching device, are provided by the support member and situated so as to mate with the latching devices when the cover is properly installed. Each recess has an internal surface at a predetermined angle to the plane of the side piece (approximately 45.degree.) against which the free ends of the prongs of the latching device can bear so as to provide a latching engagement.
