PURPOSE:To prevent easy generation of relaxation of stress in a tightening part between a nut body and a connection port part, simultaneously eliminate corrosion and rust of the nut body and the connection port part. CONSTITUTION:A connection port part 10, formed of synthetic resin of nylon 66 or the like excellent in mechanical strength and rarely generating relaxation of stress, is connected to a polyethylene-made short pipe 1. A nut body 2 is made of synthetic resin of polyacetal or the like excellent in mechanical strength and rarely generating relaxation of stress.
