A device arranged to be releasably mounting within a hole in a panel, e.g., a ceiling, to hold a lamp bulb and associated reflector or any other member therein. The device comprises a tubular body, a flange for engaging one side of the panel, and plural, equidistantly, peripherally-spaced, flexible arms for engaging the other side of the panel. Each arm extends outward from the body and is moveable from an extended position to a retracted position and vice versa. The arms are moved from the extended position to the retracted position when the body is pushed into the hole while being twisted about its longitudinal central axis in one rotational direction. The arms automatically move back to the extended position when the device is in place to hold the device securely within the hole. The device can be removed by pulling it out of the hole while twisting it about its longitudinal axis in the same rotational direction as used to insert it, whereupon the arms flex to the retracted position. An adaptor is provided for mounting in the device to hold different sized members, e.g., bulbs and reflectors.
