When inserting the insertion opening 30 into the rubber ring receiving opening 10, the insertion-side opening end of the insertion opening 30 contacts the lip 14a of the rubber insertion ring 14 to further incline the lip 14a in the insertion direction and expand the diameter. At this time, due to the friction between the outer peripheral surface of the spigot 30 and the lip 14a, the rubber ring 14 is dragged in the insertion direction of the spigot, and the portion of the rubber ring 14 in contact with the inclined wall 12c is an axis. A force that tends to rotate the compression portion 14b of the rubber ring 14 in the tube axis direction is generated. Due to this force, when the compression unit 14b rotates, rolling occurs. However, rotation of the compression portion 14b in the tube axis direction is suppressed by the pressing member 16. Therefore, no fall occurs.
