  • Retaining clip for a division bar
    Patent number: 4015388
    Abstract: A glazing division bar includes a facing member having a retaining clip secured therein and a gutter member. The retaining clip is secured in the facing member by opposed flexible legs of the retaining clip engaging an adjacent shoulder of a seal anchoring groove formed on the end of each side wall of the facing member. The retaining clip has a retaining groove formed by a bifurcated member disposed between the flexible legs for receiving arrow-shaped stem of the gutter member to secure the facing member to the gutter member about marginal edges of a glazed unit.The glazing division bar is disassembled by inserting a flat blade between a seal anchoring groove of the facing member and adjacent marginal edge of the unit into engagement with a flexible leg of the retaining clip and urging the flexible leg away from the shoulder of the seal anchoring groove to release the facing member. Thereafter the retaining clip is removed from the stem of the gutter member to free the glazed unit.
