ABSTRACT:
Disclosed is a method of fixing a pipe by means of a clamp body. A bent wall is formed by being provided integrally with a tabular clamp member in such a manner as to project from at least one portion of a pipe assembly hole bored in the tabular clamp member having a fixing portion or by allowing a separately formed cylindrical member of a short length to be inserted and fitted in the assembly hole and secured to the clamp member. In an engagingly secured state in which the pipe is inserted in the assembly hole, the projecting wall and a portion of the pipe in the vicinity of the projecting wall are clad with a heat shrinkable cylindrical piece of a short length such as an irreversible shape memory alloy or a heat shrinkable resin, and the fixing of the pipe is effected by subjecting the cylindrical piece to heat shrinkage by heating. A plurality of the bent walls constituting projecting walls may be provided at intervals, or the bent wall may be provided on each side of the clamp member. In cases where the projecting wall is formed by the cylindrical member, the cylindrical wall of the cylindrical member may be provided with a plurality of axial slits, or the cylindrical member may be provided with a collar wall projecting outwardly of its end or a substantially intermediate portion thereof.
