ABSTRACT:
A pipe joint wherein an annular connecting resin body in contact and engagement with the outer periphery of one end of at least one pipe is used for connecting the end of the pipe to one end of another pipe. The joint comprises a device for reinforcing the bond between said one pipe and the connecting resin body in addition to sanding provided for the outer periphery of the end of said one pipe. The bond reinforcing device is a barbed wire, barbed tape, piano wire or the combination of engaging grooves and engaging projections, which prevents the axial displacement of said one pipe relative to the resin body to avoid cracking due to such displacement.
