ABSTRACT:
An attachment ring for clamping a globe having a flanged neck to a lighting fixture. The attachment ring comprises an encircling member which is configured as a "C" in an open condition. The encircling member is L-shaped in cross section, the bottom of the "L" providing a ledge on which the flange of the flanged neck of the globe will come to rest. An actuator constricts the C-shaped encircling member until it is closed, thereby attaining configuration of an "O" in a closed condition. When moving to the closed condition, the encircling member frictionally engages a tubular member of the lighting fixture from the outside of the lighting fixture. Simultaneously, the ledge moves under the flange of the globe, so that the globe is constrained against falling downwardly. The actuator is operated by a manual lever, and includes a locking feature maintaining engagement of the globe.
