Abstract: An improved light cover mounting device is disclosed. A housing, capable of attachment to a light fixture, contains a compression spring and a spring-biased, retractable retaining rod. The retaining rod extends through the screw hole of a conventional light cover arrangement and engages the recessed portion of the light cover. A roll pin, projecting laterally through the housing and the retaining rod, is held at either end by L-shaped openings on the housing. The roll pin holds the compression spring inside the housing and may be hooked into the locking portion of the L-shaped openings to hold the retaining rod in the retracted position.
