PURPOSE: To eliminate unexpected separation by a detent by providing a tubular male member with an annular outer protuberance and disengaging means axially parallel and having ramps, and engaging a radial shoulder of a tubular female member with the outer protuberance. CONSTITUTION: A tubular male member 1 is provided with a protuberance 4 having a rear flank 5 and an inclined front flank 6, and disengaging member 8. Each disengaging member 8 has an extension part 11 of the protuberance 4, and a ramp 9 at the side. When the male member 1 is pushed into a tubular female member 2, an arch-like part 19 is changed into a rectangle, and a radial shoulder 21 goes over a detent part 18 and is engaged with the flank 5. When separating, one member is turned to angularly move the detent 18 on the peripheral surface of the extension part 11 to pull out the detent 18. In this structure, certainty of engagement can be confirmed, and there is no unexpected separation. |
