Claims

[Scope of claim for utility model registration] A pipe joint for connecting a branch pipe to the peripheral wall of a pipe body, which comprises a saddle portion curved approximately along the outer circumference of the pipe body, and a socket for receiving the end of the branch pipe. and a connecting part connected to a branch hole drilled in the pipe body, and a sealing member made of an elastic body and having a hollow interior is fitted to the peripheral edge of the connecting part. A branch connection pipe joint characterized in that an injection pipe communicating with the hollow portion passes through the saddle portion and is connected to the sealing member.
