Abstract

A tube clamp is constructed to include a binding strap injection-molded from high strength plastics, the binding strap having two lugs at two ends, and a smoothly arched rib-reinforced extension bearing flange forwardly extended from the first leg and adapted for supporting the second lug and guide movement of the second lug toward the first lug, a screw bolt inserted through a through hole in the first lug and threaded into a screw hole in the second lug and screwed up with a nut to fix the tube clamp to the workpiece.

Claims

1. A tube clamp comprising a binding strap adapted for attaching to the connection area of two tubular members being inserted one into the other, a screw bolt mounted in said binding strap, and a nut threaded onto said screw bolt to fasten tight said binding strap, wherein said binding strap is injection-molded from high strength plastics comprising a first end, a second end, a first lug connected to said first end, said first lug having a through hole, which receives said screw bolt, a second lug connected to said second end, said second lug having a screw hole, which receives said screw bolt, a smoothly arched extension bearing flange forwardly extended from said first leg and adapted for supporting the second end of said binding strap, and two reinforcing ribs perpendicularly extended along two sides of said smoothly arched extension bearing flange and adapted to guide movement of said second lug with the second end of said binding strap on said extension bearing flange toward said first lug.

2. The tube clamp as claimed in claim 1, wherein said second end of said binding strap comprises longitudinally spaced hook holes;

said second lug is detachably fastened to the second end of said binding strap, having at least one bottom hook selectively hooked in the hook holes in said second end of said binding strap.
