Claims

[Scope of utility model registration request]

For connecting resin-lined steel pipes, a mechanical joint with a cap nut with a perforated cam is set, and a round bar shape that is used to close the cam is used to connect the resin-lined steel pipe and the joint without twisting the joint. This is a special tool.
