To provide a pipe joint to prevent detachment of a fluid tube, which has a passage for making fluid flow and a connecting member, even if a pipe joint body is made of a resin material.

A body 12 of a pipe joint 10 is made of like a resin material. A ring member 24, and ring members 58a, 58b are installed in an outer wall portion of the body 12 by caulking, thereby preventing a deformation of the body 12 in outer direction. In the case where the pipe joint 10 is used under a high-temperature atmosphere to cause an occurrence of a force detaching a fluid tube 102 from the pipe joint 10, which force is resulted from an outer force of pressurized fluid flowing in the joint 10, thereby a fluid tube 102 and connecting member 14 inserted into the body 12 is surely prevented from pulling out.
