Humid room light has trough and cover with latching surfaces obliquely inclined to mounting plane so cover cannot be removed from trough without tools

摘要

The device has an elongated, shell-type trough (1) for attachment to a base in a mounting plane (3), a peripheral insertion enclosure (4) and a cover (2) for sealed insertion into the enclosure. The cover and enclosure have counter-latching surfaces. The cover has at least one protrusion offset relative to the latching surfaces, which are obliquely inclined to the mounting plane so the cover cannot be removed from the trough without tools.
