Abstract

A tube clamp includes a binding strap having a lead end reinforced with a reinforcing plate, a tail end, and a plurality of mounting holes at the lead end, a screw holder having a plurality of clamping plates respectively fastened to the mounting holes at the lead end of the binding strap for joining the lead end and tail end of the binding strap, and a screw mounted in the screw holder and turned to move the tail end of the binding strap relative to the lead end in tightening up the tube clamp, wherein the binding strap has plurality of transverse teeth raised from an outside wall thereof between its lead end and tail end for engagement with threads of the screw for permitting the lead end to be moved relative to the tail end upon rotation of the screw.

Claims

1. A tube clamp comprising:

(a) an elongate binding strap having a lead end section, a tail end section, and an intermediate section extending therebetween in a looped configuration, said intermediate section having a plurality of transverse teeth protruding therefrom, said lead end section having a substantially planar reinforcing plate portion and having a plurality of openings formed thereabout;

(b) a screw holder coupled to said binding strap for securing said looped configuration, said screw holder including a clamping portion substantially enveloping said reinforcing plate portion of said binding strap lead end section, said clamping portion having a plurality of clamping plates each lockingly engaging at least one said lead end section opening; and

,

(c) a screw rotatably received within said screw holder, said screw having formed thereon a plurality of threads for engaging and capturing against said screw holder reinforcing plate portion said teeth of said binding strap intermediate section, said binding strap intermediate section being advanced through said screw holder responsive to a rotation of said screw.

2. The tube clamp as recited in claim 1 wherein said teeth of said binding strap intermediate section each defines a recess therebeneath.

3. The tube clamp as recited in claim 2 wherein a first portion of said binding strap intermediate section overlaps a second portion thereof, a plurality of said teeth of said second portion respectively engaging said recesses defined beneath a plurality of said teeth of said first portion.
