Abstract: A quick coupling includes a first element and a second element which may be separably coupled. The first element includes a connector for connecting to a user interface, an external sleeve having helicoidal grooves and seats, and a first valved coupling for a first pressure line. The second element includes a hooking ring nut, a plurality of internal pins, a compression spring, a second valved coupling for a second pressure line, and a connector. The second element further comprises a safety ring nut and a plurality of safety pins provided along a circumference of the safety ring nut, the safety pins being configured to axially slide with the safety ring nut. The safety pins are configured to be pushed by the hooking ring nut and the compression spring into the seats of the external sleeve.

Abstract: A female element (1) includes a hollow internal body (2) having an end (3) provided with fastening device (5) to one of the pipes to be joined, a hollow external body (7) coaxial with the internal body (2) and having an end (8) which axially protrudes with respect to another end (4) of the internal body (2) opposite to that provided with the fastening device (5), one rigid central stem (9) coaxially supported by the internal body (2) by a transversal perforated base (18) and having a widened end (10) near the protruding end (8) of the external body (7), an axially sliding sealing bush (12) coaxially arranged about the stem (9) and elastically stressed to be engaged with the widened end (10) of the stem (9) to prevent the passage of fluid within the female element (1), a cleaning bush (14) coaxially arranged about the sealing bush (12) and axially stressed in position so as to prevent the entrance of dirt about the sealing bush (12) and a lock sleeve (16) arranged about the protruding end (8) of the external b
