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. |
