<p>PROBLEM TO BE SOLVED: To provide a semi-male fitting which can connect female fittings of the same diameter, and can connect female fittings of different diameters as well. SOLUTION: This semi-male fitting 1 is constituted roughly of a body 10, first sliding pipes 20A and 20B which are slidably fitted in the body 10, and second sliding pipes 30A and 30B which are slidably fitted in the first sliding pipes 20A and 20B. The body 10 has a stop protrubence 11 on both ends, and the first sliding pipes 20A and 20B have a female fitting removing section 21 and a stop protuberance 22, and the second sliding pipes 30A and 30B have a female fitting removing section 31 and a flange edge 32. An engagement between the stop protuberance 11 and a female fitting of a small diameter is released by the female fitting removing sections 21 of the first sliding pipes 20A and 20B, and an engagement between the stop protuberance 22 and a female fitting of a large diameter is released by the female fitting removing sections 31 of the second sliding pipes 30A and 30B.</p> |
