Abstract:
1. A device for coupling a pipe end ( 1 ) to a bore ( 3 ) provided in a fluid transport circuit element ( 4 ), the device comprising a tubular body ( 10 ) defining an inner channel ( 11 ) for receiving the pipe end, retention means ( 17 ) attached to the tubular body for retaining the pipe end in a predetermined axial position in the inner channel, and fastener means ( 23 ) attached to the tubular body for fastening the tubular body in the bore in a predetermined axial position, the tubular body fastener means being independent from the pipe-end retention means, wherein abutment means ( 22 ) for coming into abutment with the pipe end are mounted on the tubular body so as to be movable between a position in which they project into the inner channel so as to oppose entry of the pipe end as far as its predetermined axial position, and a retracted position so as to disengage the passage for the pipe end to go towards its predetermined axial position, and wherein the abutment means ( 22 ) are arranged to co-operate with the circuit element in such a manner as to pass from their projecting position to their retracted position when the tubular body is pushed into the bore as far as its predetermined axial position.
