Abstract
The invention relates to a coupling which includes at least: a tubular coupling member suitable for receiving a pipe and comprising one or more annular ribs, and a crimping ring arranged on the coupling member and translatably movable between a position for inserting the pipe into the coupling member, and a crimping position, in which the crimping ring immobilizes the pipe relative to the coupling member after the deformation of the one or more ribs. Recesses are formed between the coupling member and the pipe in the crimping position. The coupling has at least one exhaust opening arranged such as to provide fluid communication between said at least one recess and the outside of the coupling.
