ABSTRACT:
An assembly (20) for releasably interconnecting a pair of concrete form panels (28, 28a) having adjacent, apertured walls (30, 30a) is provided which completely eliminates loose parts and significantly reduces panel setup and knock-down times. The assembly (20) includes an elongated pin (22) axially shiftable between extended and retracted positions, as well as an elongated connection arm (24) of length to bridge the walls (30, 30a) and engage a surface (44a) of one wall (30a). An operating mechanism (70) is operatively coupled with pin (22) and arm (24) and serves to draw the walls (30, 30a) together when pin (22) is extended through the wall apertures (32, 32a). A latch assembly (96) serves to releasably maintain the pin (22) and arm (24) in their respective positions.
