In order to release the connection between a first tube member (12) and a second tube member (14), a ring member (40) is moved in the direction of an arrow (A), allowing the tilt surface (70A) of protrusion (70) and the tilt surface (66A) of protrusion (66) on a cam section (56) to slide and a stopper (52) to rotate in the direction from the engagement position to the non-engagement position. As a result, the engagement between the tip (54A) of the claw section (54) on the stopper (52) disposed on the second tube member (14) and the engagement surface (21C) of the section (21) to be engaged on the first tube member (12) releases. Meanwhile, in order to connect the second tube member (14) with the first tube member (12), the ring member (40) functions as a locking position, and the first tube member (12) is pushed into the second tube member (14) causing the claw section (54) of the stopper (52) to elastically deform. As a result, the tip (54A) of the claw section (54) slides over the section (21) to be engaged and engages with the engagement surface (21C) of the section (21) to be engaged. |
