To provide a pipe joint which can be easily assembled and can maintain the connection of pipes firmly while simplifying the pipe connecting work. Tapered surfaces 6 which reduce in diameter toward openings 2 are formed on inner peripheral portions of half portions of a tube 1 in order to join pipes A and B together, and a diameter-reducible elastic wedge ring 7 is disposed on the large inside diameter portion of the tapered surface 6. In order that when the pipes A and B are about to slip out, the wedge rings 7 are pressed out along the tapered surfaces 6 to reduce a diameter thereof, rubber rings 10 capable of being placed in close contact with the pipes A and B are engaged with and held on sliding rings 8 capable of sliding smoothly along the inner periphery of the tube 1 and provided adjacent to the wedge rings 7. When the wedge rings 7 assume a diameter-reduced state, they are encroached on the outer peripheral surfaces of the pipes A and B to prevent the pipes from slipping out.
