Patent ID: 8882080

Claim:
A connecting device adapted to transmit pressurized gaseous and/or liquid fluids, the connecting device being configured to be coupled with a connecting end provided with an engaging profile, with a first element among the connecting device and the connecting end that is configured as a male element and a second element among the connecting device and the connecting end that is configured as a female element, the connecting device comprising: a tubular body that extends along a longitudinal axis between a front side facing the connecting end in the coupled configuration and a rear side facing opposite the connecting end in the coupled configuration, a control member that slides relative to the tubular body along the longitudinal axis, at least one coupling member that includes an engaging profile complementary to the engaging profile of the connecting end, and wherein the engaging profile of the at least one coupling member and the engaging profile of the connecting end are complementary threads and tappings which have an identical apical angle and thread pitch and wherein the axial play is greater than or equal to a half-pitch of the threads and tappings, and elastically deformable means that push the control member back toward the front side in a maintenance position of the a least one coupling member locked on the connecting end and which push the at least one coupling member back toward the rear side against a surface of the tubular body in a position, when a passage for the connecting end is freed by the at least one coupling member, where an axial play is defined between the at least one coupling member and the tubular body, the axial play allowing an axial movement of the at least one coupling member relative to the tubular body and against the elastically deformable means acting on the at least one coupling member toward a position locked on the connecting end.
