る。According to this structure, the state where the one end of the tightening ring 1 is inserted into the circumferential groove 3 on the other end side can be held against the elastic reducing force of the tightening ring 1. At that time, in particular, the elastic expanding force of the tightening ring 1 is applied to the engaging hole 24 of the locking claw portion 23.
Since it can be used as a force in the direction of increasing the engagement depth to the circumferential direction, it is possible to reliably hold the state where one end of the tightening ring 1 has entered the circumferential groove 3, and therefore these engaging parts.
Even if an impact force in the direction of the generatrix of the tightening ring 1 acts on 2 1 , 2 2, etc.,
It is possible to reliably prevent the disengagement between the first and second engaging portions 2 1 and 2 2 and to maintain the expanded diameter state of the tightening ring 1 extremely stably.

Effect of the Invention As described above, according to the present invention, the locking claw portion at the tip of the locking piece integrated with the second engaging portion is fitted and locked in the engaging hole of the first engaging portion. The state in which one end of the tightening ring connected to the first engaging portion is inserted into the circumferential groove on the other end side of the tightening ring can be retained against the elastic reducing force of the tightening ring. At that time, in particular, since the elastic expanding force of the tightening ring can be made to act as a force in the direction of deepening the locking depth of the locking claw portion into the engaging hole, one end of the tightening ring can be tightened. The state of entering the circumferential groove on the other end side of the annulus can be reliably held, and therefore even if an impact force in the direction of the tightening annulus acts on these engaging parts and the like, It is possible to reliably prevent the disengagement between the two engaging portions and maintain the expanded state of the tightening ring extremely stably.
