ABSTRACT:
A safety belt clamp apparatus including crossed arms operatively interconnected for scissor-like motion for grasping a beam. Connecting members pivotally attached to the end of the arms include openings for receiving a safety belt clip, so that pressure exerted on the clip away from the beam urges the clamp apparatus into tighter engagement with the beam. Additional rings are provided so that more than one person can be connected to a single clamp apparatus. In one embodiment of the invention, a diagonally extending brace and jaw assembly provides additional structure so that the clamp apparatus can be attached to a vertically extending beam.
