PURPOSE: To integrate a main section and a subsidiary section without application of ultrasonic waves by arranging a part of the throughway having a tapered internal cam surface in the subsidiary section and deforming it inwardly to lock the other end of the subsidiary section in the receiving opening of the main section through a collet. CONSTITUTION: A tube coupling 10 has a body 12 formed by a main section 12a and a subsidiary section 12b. The subsidiary section 12b has one end 22 engaging with an annular seat portion 20 of the main section 12a, and another end 23, and has a tapered internal cam surface 25 of a throughway 13. A collet 26 extends into the throughway 13 of the subsidiary section 12b and is engageable with the tapered internal cam surface 25 in the subsidiary section 12b, to push a head 28 inwardly and engage and hold a tube 11 in the collet 26. When the collet 26 is moved outwardly, the pipe 11 is locked in the body 12. |
