PROBLEM TO BE SOLVED: To reuse other components only with replacement of a few consumable component, and repeatedly perform pipe connection to a pipe body.SOLUTION: A sleeve 20 is divided into a cylindrical member 21 which is engaged to a projection part 12 of a joint body 10 in an unrotatable manner and to which a fastening member 30 is engaged in a movable manner, and a diameter contraction member 22 that is subjection to diameter contracting deformation by movement of the fastening member 30, and the cylindrical member 21 and the diameter contraction member 22 are arranged so as to connect them in an axial direction. Every time when a deformable pipe body B is connected to the sleeve, the sleeve is repeatedly used. With the repeated use, even when the diameter contraction member 22 plastically deforms, by replacing only the diameter contraction member 22, the pipe body B can be repeatedly connected with reuse of other components such as the cylindrical member 21.SELECTED DRAWING: Figure 1 |
