It is known to hold a trough-shaped, transparent cover in the housing of an elongate lighting device with the aid of hook-shaped springs. The invention enables other covers as well, such as louvers or prismatic panel diffusers, to be held in such an unchanged housing; it consists in constructing the side walls (21, 22) of a frame (200) for such covers (4) in the same way as the side walls of the trough-shaped cover. <IMAGE> |
