A safety anchor including a pair of rectangular plates connected by a spring-loaded hinge assembly which normally biases the plates toward one another in a completely folded configuration. Each plate defines an aperture aligned with the opposing aperture when the plates are completely folded together. A double locking safety hook may be clipped through the apertures, and prevents the plates from being unfolded. Each plate includes a retention post fixedly attached thereto and extending outwardly beyond the rear edge of the associated plate. Each retention post has an enlarged head with two flat surfaces. The flat surfaces may be aligned with the slot in the beam and inserted therethrough into a recessed cavity when the plates are completely unfolded. When the plates are then folded together, the retention posts rotate relative to the slot and the enlarged heads become engagingly retained within the recessed cavity and behind the narrower slot. The spaced-apart retention posts prevent rotation or rocking of the safety anchor. During a fall, the plates of the safety anchor will cam against the face of the beam, and the hinge assembly will bear no load. Once the safety link is detached, the safety anchor may be removed and remounted on another beam using only one hand. The safety anchor is particularly suited for use with horizontal slotted beams and associated components utilized in erecting concrete pouring forms of the type referred to as "flying forms."
