Abstract
A lighting fixture employing a cover or lens, preferably of flat glass or plastic. A slidable or pivotal retaining clip is provided for either opposite corners or for each corner of the cover. Each clip acts to hold the cover lens without the need for a surround frame. The retainer clips are slidable or pivotal between a hold position clamping the lens to the fixture body and a release position in which the fixture is freed of the retaining or clamping action of the clip. In the release position, the clip is held on the face of the fixture by holding stops on the fixture body.
