ABSTRACT:
A coupler (for joining tubing to a shoring leg or the like, having a T-shaped bolt slot extending along the length of such leg) is formed of a sickle-shaped metal strap or extrusion, having a C-shaped central portion, a radial extension portion at one end, and a tangential T-portion at the other end, said T-portion being formed of a head and a relatively narrow neck with adjacent opposing shoulders; and a T-bolt secured through a hole in the extension portion. The head and shoulders defining the neck of the T-portion are spaced and shaped so as readily to accommodate therebetween the lips forming the T-slot when the T-portion is inserted generally perpendicularly into the T-slot and yet grippingly bite into said lips when the coupler falls into the cocked open position. This permits the coupler provisionally to cradle and hold the tubing in place before the T-bolt is fastened. Advantageously, the coupler is hinged between the C-portion and the T-portion, thereby assuring that the T-portion continuously grips against vertical movement in the vertically disposed T-slot, even during fastening of the T-bolt.
