Claims

[Claims for Utility Model Registration] A ribbed tube having a large number of annular ribs on its outer circumferential surface;
This is a connection structure with a branch connection pipe joint for connecting a branch pipe to the peripheral wall of the ribbed pipe, wherein the branch connection pipe joint is curved approximately along the outer circumference of the rib of the ribbed pipe, and has edges on both ends. It consists of a saddle part in which a locking piece facing inward is formed on each side, and a branch pipe connection part protruding from the outer surface of this saddle part, and a branch hole is formed in an appropriate position on the circumferential wall of the ribbed pipe. At the same time, locking grooves that engage with the locking pieces of the branch connection pipe joint are formed on both sides of the branch hole by partially cutting each of the ribs along the pipe axis. The saddle part of the branch connection pipe joint is fitted into the ribbed pipe, and the locking piece of the saddle part and the locking groove of the ribbed pipe are engaged, so that the inner surface of the saddle part becomes ribbed. A connection structure for a branch connection pipe joint, characterized in that the branch connection pipe joint is connected and fixed to a ribbed pipe while being crimped to the rib outer periphery of the pipe.
