Claims

[Scope of utility model registration request]

A joint that has an end clamping part and a middle clamping part that connect resin-coated steel pipes in at least two axial directions, and has at least two split joint pieces that are fastened and fixed to each other, and that is fitted to the end of the resin-coated steel pipe. The cap to be attached is held between the end holding parts, while the sleeve to be fitted to the intermediate part of the resin-coated steel pipe is held between the intermediate holding parts, and the outer circumferential surfaces of the cap and sleeve and the inner circumferential surfaces of the respective holding parts are What is claimed is: 1. A joint comprising: an engaging concave portion or a convex portion that engages with the two to prevent movement in the axial direction; and an engaging convex portion or concave portion.
