摘要

PROBLEM TO BE SOLVED: To firmly connect a tube and a male connector regardless of the wall thickness or outer diameter of the tube.;SOLUTION: The approximately tube-shaped male connector 100, which has an insertion part 103 at one end to be inserted into the tube and whose other end is a proximal end 104, is inserted into a lock part 200. The lock part is rotatable relative to the male connector. The male connector has at least one first swelling part 130a swelling in such a way that the distance from a center axis increases as seen along the direction parallel to the center axis in a part of the outer surface of the insertion part. The lock part has at least one second swelling part 230a swelling in such a way that the distance from the center axis increases as seen from the direction parallel to the center axis on the outer surface of the lock part. The distance from the center axis to the apex of the first swelling part of the male connecter is identical to or larger than the distance from the center axis to the apex of the second swelling part of the lock part.;COPYRIGHT: (C)2010,JPO&INPIT
