The fitting protruding part 8 and the fitting recessed part 7 provided in the joint part 6 are mutually fitted into the fitting recessed part 7 and the fitting protruding part 8 of connection fitting main bodies on mate sides in the axial direction. Locking hook parts 9 which regulate travel in the axial direction by locking into the fitting protruding part 8 of the connection fitting main body on a mate side in the peripheral direction and lock a pair of these connection fitting main bodies in the axial direction are provided in these fitting protruding parts 8. Tip parts of the fitting protruding parts provided protrudedly in the axial direction of the pair of connection fitting main bodies do not have a plane being the same in the axial direction of the connection fitting main bodies and have a ridge line going toward a central axis of the connection fitting main bodies.
