The pipe joint of the invention comprises a push ring, having a protrusion on outer circumference and fitted into the outer circumference at one end of junction pipe, a pipe and pipe joint main body, having a protrusion facing the protrusion at the side facing the push ring, having a pipe receptacle expanding toward the push ring at the inner side of this protrusion, and fitted to the outer circumference of the junction pipe across a peripheral gap, a clamp, capable of moving and operating the push ring in a direction of the pipe or pipe joint main body, a packing ring, disposed between inner and outer circumference of the pipe or pipe joint main body, and junction pipe, and fitted into the pipe receptacle by the own elastic deformation generated by the pressing force of the push ring moving by operation of the clamp, and an anti-slip ring disposed between inner and outer circumference of the push ring and junction pipe, and separated at one position in the circumferential direction, in which the push ring is an annular form not having separated position in the peripheral direction, and a tapered push ring receptacle spreading toward the pipe or pipe joint main body at its inner peripheral side, an elastic member is disposed between the push ring and packing ring, and by the own elastic deformation caused by pressing force of the push ring moved by operation of the clamp, the anti-slip ring is compressed to the junction pipe outer surface, and a spacer is disposed between the packing ring and elastic member, and abuts against the receptacle peripheral outer surface by pressing force of the push ring moved by operation of the clamp.
