ABSTRACT:
A clamp for securing adjacent sides of a pair of structural members such as metal tubing. The clamp comprises of a pair of fastening devices joined together, back to back. Each fastening device further comprises an inwardly contactible sleeve with the back side being flat where it is joined. From the backside two sides are turned to enclose a structural member and form an opening to facilitate entry of the structural member. At opposite sides of the opening a pair of wedge flanges are turned outwardly with diverging tapers. Each sleeve has a contractor with inturned flanges which taper in opposition to the taper of the sleeve flanges. The contractor when slid onto the sleeve flanges draws itself and the sleeve into a constricting gripping engagement with the enclosed structural member.
