ABSTRACT OF THE DISCLOSURE A safety key designed specifically for use in connection with concrete wall form panels of the "Steel-Ply" or metal- encased type. The key affords an anchor eyelet or hole for receiving the hook which invariably is provided on one end of a safety belt that is worn by a workman who is obliged to work on the concrete wall form at an extremely high or unsafe level or elevation. The key in one form of the invention embodies a shank and an enlarged head, the shank being received in the opposed notches which are formed in the outermost abutting ribs of the mating and abutting frame members or bars of the marginal reinforcing frames of two adjacent wall form panels, and being removably locked in place by a pair of conventional coacting wedge bolts. The enlarged head on the shank defines the aforementioned anchor eyelet or hole. Alternatively, the shank of key is capable of being received through a pair of registering bolt-receiving slots in such mating and abutting frame members or bars and of being locked in place by a single wedge bolt.
