QUICK-COUPLING COCK AND COUPLING TUBE INTERACTING WITH SAID COCK

摘要

A quick coupling cock (1) intended to interact with a coupling tube (2) to connect a compressed air distribution network (D) to a user (U) is disclosed, comprising a cock body (3) communicating with the distribution network (D), in which a coupling tube (2) communicating with the user (U) is slidingly received; contrast means (5) adapted to constrain the coupling tube (2) in the cock (1); a sliding sleeve (6) externally coupled to the cock body (3) and to the end (4a) of a tubular body (4) inserted in the cock body (3) receiving the coupling tube (2). The sliding sleeve (6) comprises a tubular ring nut (15) coupled to the cock body (3) and a tubular lock ring (16) coaxially aligned with the ring nut (15) and coupled to the tubular body (4). The tubular ring nut (15) and the lock ring (16) are coaxially coupled one inside the other for a common stretch (17) in which there is a discharge way (18) of the cock (1).
