The flange 11 of one joint body 10 involves a bolt seat hole 12 and temporary locking pins 13. The flange part 21 of the other joint body 20 includes bolt through-holes 22 and an engagement hole member 23. When the end parts of the two corrugated pipes are clamped by the joint bodies 10, 20, the temporary locking pins 13 invades/engages with the engagement hole member 23, so that the joint bodies 10, 20 are locked temporarily.</p> |
