PROBLEM TO BE SOLVED: To provide a pipe joint by which an outer diameter of a pipe connecting part can be reduced, and high drawing strength can be obtained. SOLUTION: A pipe joint comprises a stopper 4 to be mounted in a groove of a wavy pipe 1 without loose, and a sleeve 5 into which an edge part of the pipe 1 on which the stopper 4 is mounted, is to be entered. The stopper 4 comprises a locking projection piece 7 projecting outside of the sleeve 2 in a condition that the stopper is mounted in the groove 2. The sleeve 5 comprises an opening 7 into which the locking projection piece 6 is entered, and an inner diameter of the sleeve 5 is determined to be smaller than a diameter of a circumscribed circle passing an outer edge of the locking projection piece 6. When an edge part of the pipe 1 on which the stopper 4 is mounted, is to be inserted into the sleeve 5, the insertion can be made possible by the elastic deformation of the locking projection piece 6 in a radial direction, the original shape is recovered when the locking projection piece 6 is entered into the opening 7, and the locking projection piece 6 is hanged on an edge of the opening 7, whereby the drawing can be prevented. |
