<p>PROBLEM TO BE SOLVED: To provide a clamp device for a pipe coupling to reduce size and weight and be excellent in operability. SOLUTION: A clamp device for a pipe coupling is formed such that the half-periphery of a resin pipe is wound around by a chain one end of which is fixed, and the resin pipe is fixed by drawing the other end of the chain. In this case, one end of a chain 33 is fixed at one end of a coupling member extending through a fixed member 35, the other end is coupled to an eccentric cam 52 arranged at a press member 50 through a tension member 53, and a slit in a longitudinal direction is formed in the fixed member 35. A slit is also formed in a coupling member and fixing is effected so that a coupling member is prevented from rotation based on the fixed member 35 by a lock plate inserted in slits formed in the fixed member 35 and the coupling member.</p> |
