Hose coupling incorporates male part and a female part being provided with means which in corporation with a slide axially displaceable sleeve on the female part renders possible pressure relief at disconnection. This means in the coupling is constituted by an angular locking pawl one portion of which is insert able in an axial groove in the female part and has such length that always at least some part thereof is surrounded by the sleeve. The other inwardly directed part of the locking pawl has such length that it extends into the groove of the male part when the locking pawl is influenced by the sleeve. The locking pawl is a combined means, to lock the male part when the coupling is connected and lock the male part in an alternative position when it's pressure relieved. |
