Abstract

PROBLEM TO BE SOLVED: To perform high-efficient connection of a pipe body without cutting off a flow in a fluid pipe. SOLUTION: Since a moving means 21 for a sleeve 20 is arranged in a fluid pipe 1 or a member 32 for a fluid pipe, the structure of a closed case is simplified and a work to mount on the fluid pipe 1 and demount therefrom is facilitated and the cut-off ability of the closed case is improved. Further, since a moving means 21 is constantly mounted on the vicinity of the sleeve 20 regardless of the length of the cut part of the fluid pipe 1, the sleeve 20 is movable further reliably in a short time.
