ABSTRACT:
A fast-fit coupling for a fluid circulation system comprising at least two conveying members of a fluid. The coupling comprises: a receiving body for each conveying member; way for fastening carried by the body, shiftable by the conveying member during the insertion of the conveying member, and integral with the conveying member when the conveying member is moved in a disconnection direction from the body; way for locking cooperating with the way for fastening to lock the conveying member in a position inside the body and to prevent the body itself from being disconnected; and way for releasable constraint, activatable for restraining the way for locking to the body and preventing the conveying member to be disconnected, and deactivatable to disconnect the way for locking and allowing the conveying member to be disconnected; the way for locking and the body are engageable/disengageable by ways of a relative rotation less than ninety degrees.
