をコンパクトに纏めることができるという利点がある。It is conceivable to increase the cross-sectional area of the conventional pipe joint (see FIG. 10 et seq.) By lengthening the connecting region 24 to avoid breakage.
The force for expanding the distal end of 23 becomes large, and there is a problem in use that the insertion of the tube 22 is hindered. On the other hand, in order to reduce the force for expanding the tip of the claw portion 23, it is necessary to set the length of the claw portion 23 longer in order to disperse the stress, and the overall length becomes longer. According to this, there is an advantage that the entire length can be made compact while preventing destruction.
