PROBLEM TO BE SOLVED: To provide a pipe joint with a plug prevented from rotating relative to a socket without requiring complicated work for shaping the plug and narrowing an internal flow path of the plug. SOLUTION: The pipe joint 10 comprises the approximately tubular socket 11 to be mounted at one pipe end, the approximately tubular plug 12 to be mounted at the other pipe end inserted into the socket, a come-off preventing means 13 for preventing the come-off of the plug from the socket, a seal ring 14 arranged on the inner periphery of the socket, and a pressure ring 15 arranged on the inner periphery of the socket for preventing the movement of the seal ring. A protruded portion is formed at a pressure ring mounting position on the inner periphery of the socket. The pressure ring has a cut-off portion 46 or a recessed portion to which the protruded portion is fitted and a protruded portion 47 protruded in the direction of a plug insertion hole. The plug has an annular protruded portion 33 with which the come-off preventing means engages and a recessed portion or a flat portion provided on the annular protruded portion for engaging with the protruded portion of the pressure ring.
