Abstract
The coupling includes a peripheral locking gasket for the pipe, the gasket being elastically deformable from a state in which it has a nominal inside diameter; an outer clamping ring placed on the end of the pipework element and surrounding the gasket; and a mechanism for thrusting the clamping ring axially towards the pipework element. The coupling has a spacer for holding the gasket spaced apart with an inside diameter greater than its nominal diameter before the pipe is put into place, the spacer being releasable once the pipe is in place.
