摘要： A coupling for connecting a first pipe part and a second pipe part comprises a first coupling part and a second coupling part, a shut-off valve arranged in the first coupling part, and locking structure. The locking structure can move with respect to one another between an unlocked position and a locked position, in the manner of a bayonet coupling. An actuator for actuating the shut-off valve is arranged in the second coupling part. The locking structure and the actuator are designed in such a manner that the shut-off valve can only be opened by means of the actuator when the locking structure is in the locked position, and in that the coupling can only be uncoupled when the shut-off valve is in the closed position. The actuator and the locking structure can be actuated separately.
