A self-venting rapid connection-release coupling for pressurized gas lines, and in particular compressed air lines, has a coupling socket (1) and a coupling plug (2). The coupling socket is provided with two locking devices (22, 23) for the coupling plug (2), and these devices can be released in succession by a motion, in the same direction, of a slider sleeve (30) on the coupling socket (1). Moving the slider sleeve from a start or coupled position to an intermediate position, a first locking device (22) is released, but the slider sleeve (30) is arrested by a locking element (47), and the plug is held by the second locking device (23). The lockig element (47) is controlled as a function of the gas pressure in the coupling plug (2), until the gas pressure in the coupling plug (2) and the line to the severed compressed air line has been reduced by venting through venting conduits (51, 53). Only after the pressure has been released and vented, can the slider sleeve (30 ) be moved to a position permitting release of the coupling plug (2) from the socket (1).

Self-venting rapid coupling for compressed gas lines having a coupling plug (2), adapted for connection to a first gas line; a coupling socket (1) receiving said coupling plug (2), and adapted for connection to a second gas line subject to pneumatic pressure; a valve (10) located in the coupling socket (1) engageable by the coupling plug, said coupling plug holding the valve in OPEN condition when the coupling plug is inserted in the coupling socket; a first locking device (22) having at least oe first locking element (24) secured to the coupling socket to lock the plug to the socket, when inserted therein; a second locking device (23) having at least one second locking element (39) secured to the coupling socket for locking the plug to the socket; a slider sleeve (30) located on the coupling socket (1) and axially slidable thereon; spring bias means (14) acting on the slider sleeve (30), the slider sleeve (30) being operatively coupled to the first and second locking devices (22, 23) and movable counter to the spring force of the spring bias means (14) from a) a start position, in which the coupling plug (2) is retained by the first locking device (22) in locked position in the coupling socket (1) with the valve (10) in open condition, to b) an intermediate position, wherein the coupling plug (2) is retained by the second locking device (23) in locked position while still at least partly inserted in the socket (1), and in which the valve (10) is in closed condition, the first locking means (22) and the first locking element (24) are released from locked position; and to c) a second or released position in which the coupling plug (2) can be removed from the coupling socket (1), comprising, in accordance with the invention, a venting means (51, 55, 56); a movable further locking element (47) located on the coupling socket (1) and forming an axial abutment for the slider sleeve (30) when the slider sleeve (30) is in the intermediate position, said movable further locking element (47) being subject to pneumatic pressure in the first line coupled to said coupling plug (2) when the valve is open, said movable further locking element (47) being retained in abutting condition with respect to the slider sleeve (30) to arrest the sliding movement of the slider sleeve (30); and wherein, upon closing of the valve (10), said movable further locking element (47) is released from pneumatic pressure, the second line is vented through said venting means (51, 55) and the movable further locking element (47) moved to release position to permit movement of the slider sleeve (30) to the second or plug release position.
