摘要： At a hose coupling incorporating male part (10) and female part (11), the latter includes an automatic nonreturn valve (13), which opens at inserting of the male part. A displaceable sleeve (14) enclosing the female part acts firstly upon locking pawls (16) that retain the inserted male part, and secondly upon locking bodies (17) which at disconnection transiently permits blowing off of the air pressure in the coupling. The locking pawl (16) is T-shaped and insertable in a corresponding cross formed groove (24) in the female part (11), the cross beam (23) of the locking pawl has smaller thickness than the web portion (21) and this is below the cross beam made thicker to a transversal ridge (22), which in coupling position cooperates with a circumferential locking groove (12) in the male part (10).

摘要： Hose coupling incorporates male part (10) and female part (11) being provided with means (16, 117), which in cooperation with a slide (14) axially displaceable on the female part renders possible pressure relief at disconnection. One of these means in the coupling is constituted by an angular locking body (117) one portion (20) of which is insertable in an axial groove (23) in the female part and has such a length that always at least some part thereof is surrounded by the sleeve (14). The other inwardly directed part (21) of the locking body, has such a length that it extends into the groove (15) of the male part when the locking body is influenced by the sleeve (14).

摘要： The invention refers to a hose coupling for compressed air, which has a safety locking device. The safety locking consists in that when the male member (1) is disconnected, the male member (1) is not entirely disengaged but is caught by the locking balls (4) in the female member (2) until the overpressure in the hose and the tool has disappeared. Then the male member (1) is released. In this way the unpleasant bang that otherwise arises, and the effect that the hose together with the male member (1) moves backwards with enormous power, are prevented in a controlled way.
