摘要： The present invention relates to a device for blocking a liquid- and/or vapour-flow from a hose and positioning a hose rupture to a coupling in the hose, e.g. the end of the hose and a nozzle, the coupling comprising a female fitting (2) and a male fitting (1), each with its radial, at least partly conical portion (6, 7) which, after union of the male fitting (1) in the femal fitting (2), form at least parts of a conical ring, a split ring (10) consisting of one or more parts and provided with a groove (11) fitting the conical ring, being disposed on the conical ring (6, 7) for interconnecting and retaining the male fitting (1) in the female fitting (2), the ring (10), on the opposite side in relation to the groove (11), having at least one groove (12, 27, 28) each for a spring ring (13, 29, 30) for orientation of the string ring (13, 29, 30) and urging the ring (10) against the conical ring (6, 7) and retention of the male fitting (1) in the female fitting (2) until a predetermined separating force occurs, when the split ring (10) slides off the conical ring (6, 7) so that the retention of the male fitting (1) in the female fitting (2) ceases, a valve cone (3) being disposed to block liquid- and/or vapour-flow in the event that the male fitting (1) and the female fitting (2) are parted from one another, and the valve cone (3) having coupling elements (19) for engagement with the female fitting (2), and a sealing element (18) for co-operation with a sealing surface in the male fitting (1), or vice versa, and an indication of fracture (21) being located between the coupling elements (19) and the sealing element (18).
