PROBLEM TO BE SOLVED: To surely connect pipes in a compact manner. SOLUTION: In a configuration in which a socket part 6 is provided at a connection end of a pipe 1 on one side out of a pair of corrugate pipes 1, 1 to be connected mutually, an insertion part 1A whose diameter is shrunk is provided at a connection end of the pipe 1 on the other side, and an insertion end part of the pipe 1 on the other side is internally inserted into the socket part 6 of the pipe 1 on one side to connect both pipes 1, 1, an inside diameter d2 of the socket part 6 of the pipe 1 on one side is set to be substantially equal to an outside diameter d2 of a projection part 2 of the insertion part 1A of the pipe 1 on the other side, and an outside diameter d1 of the socket part 6 is set to be substantially equal to an outside diameter d1 of the projection part 2 in a part other than the insertion part 1A of the pipe 1 on the other side so that the socket part 6 does not protrude from outer periphery of the corrugate pipe 1. |
