<p>PURPOSE:To obtain a fastener capable of safely, surely and automatically connecting members in the fastener having plural cylindrical members which are relatively detachably provided and for a means for clamping the flanges of the members by specifying the structure of the clamping means. CONSTITUTION:This fastener has the first member 6 and second member 7, the first flange F6 and second flange F7 at the ends, an elastic sealing material between both flanges and a means 21 for clamping both flanges. The clamping means 21 is furnished with a connecting member 23 normally held by an elastic body 24 at a position not projecting from a first opening K1 furnished to the first flange F6, a first actuator 26 for projecting the connecting member 23 from the first opening K1 which is thereby allowed to pierce the second opening K2 of the second flange F7, a detaining member 30a to be engaged with a through-hole 23a formed in the connecting member 23 to unregressively hold the member 23 and a second actuator 31 to advance or retreat the detaining member 30a with respect to the through-hole 23a.</p> |
