PROBLEM TO BE SOLVED: To provide a pipe joint capable of simplifying and miniaturizing a structure, and exerting basic sealing performance and pipe pull-out resistance.SOLUTION: A pipe joint is composed of only two components of a pipe joint body 2 and an outer cylindrical body 5. The pipe joint body 2 has a tapered internally-inserted cylindrical portion 4 inserted to an end portion 3 of a pipe P made of a resin material. A plurality of annular independent projections 11 are formed on an outer peripheral face of the internally-inserted cylindrical portion 4, a plurality of axial small projections G for preventing corotation of pipes, are formed on a basic end portion of the internally-inserted cylindrical portion 4, and the outer cylindrical body 5 has an internally-threaded projection 7. The outer cylindrical body 5 is screwed while forming a spiral groove 20 on an outer peripheral face of the pipe P, and connected to the pipe joint body in a final fastening state. |
