ABSTRACT:
An improved, lightweight, retrofittable pin assembly (10) for the releasable interconnection of end-to-end abutting concrete form panels (12, 14) is provided which includes an elongated, tapered, axially shiftable pin (16) as well as coupler (18) for coupling the pin to an end wall (24) of a panel (12). The coupler (18) includes a resilient metallic retaining ring (58) which frictionally and compressively engages the pin in substantial alignment with an associated aperture (27) in end wall (24). The pin (16) preferably includes a pair of elongated, opposed sots (34, 36), and a two-piece, split tab washer (60) is employed for preventing complete detachment of the pin (16) from assembly (10) during use thereof.
