Abstract: A clip to be installed on a diffuser such that a lip defined by the rim of the diffuser is positioned in a cavity of the clip, with two arms defined by the clip capturing the rim of the diffuser and a leg defined by the clip extending into the hollow center of the diffuser. The diffuser may include knobs positioned on either side of the clip to prevent the same from sliding. The leg of the clip is then placed in an inverted channel defined by the lighting fixture such that the clip secures the diffuser thereto.

Abstract: Apparatus for molding plastic caps having inclined tabs integral with the lower edge of the cap skirt and radially inwardly extending ribs integral with the inner surface of the cap skirt. The tabs and ribs are formed by a plurality of blades having recesses on the ends thereof corresponding to the configurations of the tabs and ribs. The blades are mounted on a core and extend into a female mold having a cup-shaped cavity. A linear drive member is mounted on a fixed plate assembly and connected to a ratchet sleeve rotatably mounted on a movable plate assembly. The end of the ratchet sleeve is provided with circumferentially spaced teeth engaging the lower peripheral edge of the cap skirt. Movement of the movable plate assembly relative to the fixed plate assembly causes the ratchet sleeve to rotate to move the molded tabs and ribs away from the recesses of the blades so that the finished cap can be stripped from the apparatus.
