To protect a bellows pipe by effectively supporting a load, exerted on a coupling part with a pipe material, without increasing the size of an outside diameter.
In a coupling part between a pair of pipe materials 1 and 2, a cover member 4 to cover the outer peripheral part of a bellows pipe 3 through which two pipe materials 1 and 2 are interconnected at a coupling part between a pair of the pipe materials 1 and 2 is mounted on the end part of the pipe material 1. An inner circumferentially protruding protrusion part 13 is arranged at the tip part of the cover member 4, and a regulation member 5 to regulate longitudinal movement of the protrusion part 13 and energizing members 20 and 21 consisting of a disc spring to energize the protrusion part 13 axially of the bellows pipe 3 are arranged at the end part of the pipe material 2.
