<p>PROBLEM TO BE SOLVED: To provide fixing jig and method for a resin tube into a roundness condition even the tube to be fused is not in the roundness condition, to fuse the tube correctly. SOLUTION: In fixing jig, a halved sleeve 5 having rigidity and cylindrically nipping a resin tube 1 is mounted on the outer peripheral surface of the tube on the side opposite to a saddle joint 2 astride the tube 1, and an engaging member 3 is mounted from the outer surface of the sleeve 5 to be locked to a saddle joint 2, to fix it to the outer peripheral surface of the tube 1. A clamp member, having rigidity and cylindrically nipping the outer peripheral surface of the tube 1, is mounted on the longitudinal directional side part of joint 2, and a linking means detachably linking the clamp member is provided on the sleeve 5 to link between locking parts of the member 3 and of the upper surface of the joint 2 into a given dimension. In this fixing method, the outer peripheral surface of the tube 1 is sylindrically nipped by the clamp member, and the semicircular sleeve 5 is mounted on the outer peripheral surface on the opposite side of the joint 2, and also is linked to the crank member, to lock the member 3 to the joint 2 from the outer surface of the sleeve 5, thereby locking the joint 2 to the outer surface of the tube 1.</p> |
