Abstract
A coupling which can be used in fueling lines (L1, L2) or the like, the coupling having a closure device which blocks the flow path of the fluid and are brought automatically into closed position as a function of a sensor-recorded displacement of the feed line with respect to the discharge line; in order to achieve a functionally optimized solution, the coupling is developed as rapid-closure coupling (K) having an ejector ram (41) acted on by pressure fluid as a result of the action of a sensor, for the separation of the two coupling halves (I, II) which have previously been brought individually into the closed position (closing of the shut-off valves V1, V2), also due to the action of a sensor.
