Claims

[Scope of Claim for Utility Model Registration] A branch connection pipe joint for connecting a branch pipe to the peripheral wall of a pipe body, which includes a branch connection pipe to which the end of the branch pipe can be connected, and a branch hole drilled in the pipe body. It consists of an inner tube to be attached, an insertion section into which the inner tube and branch connection tube can be inserted, and a saddle section curved at the proximal end of the insertion section so as to roughly follow the outer circumference of the tube body. , a locking protrusion is formed on the inner pipe to prevent it from falling into the branch hole, and a contact portion whose diameter is expanded and contracted in the direction of expanding the diameter of the branch hole is provided, while the branch pipe connection 1. A branch connection pipe joint, characterized in that the pipe is formed with a flange portion that abuts an edge of the insertion portion, and the branch pipe connection pipe and the inner pipe can be screwed into each other.
