Abstract
A pipe joint has a pipe 11 including an outward facing flange 17, a joint body 10 and a tubular metal fixture 20, and the joint body 10 includes a large opening port 12 and a small opening port 13 concentrically in consecutive order from the end side. The tubular fixture 20 has a stopping portion 22, a springy first claw 21 and a springy second claw 23; and the joint body 10 has a fitting groove 10a in which the first claw 21 fits. Therefore, an assembly work can be simplified, and fingers and jigs can be prevented from being caught in.
