Abstract: A pipe joint for coupling to at least one pipe is disclosed in the present invention. The pipe joint includes a main body and at least one positioning socket. The main body has a runner and at least one opening communicated with the runner. The runner has an insertion area adjacent to the opening. The positioning socket has a head, an inserting portion, a pipe channel, a radial threaded hole and a bolt. The inserting portion is inserted into the runner via the opening. The pipe channel runs through the head and the inserting portion in an axial direction of the positioning socket. The threaded hole is formed on the head and communicated with the pipe channel. The bolt is adapted to engage with the threaded hole for abutting against the outer surface of the pipe.
