The invention relates, in general, to couplings for the connection of lines, such as, in particular, flexible lines, to one another or for the coupling of flexible lines to fittings. For this purpose, a quick-action coupling (1) for coupling together fluid-conducting lines is described, which comprises a first coupling part (3) and a second coupling part (5), as well as a seal (7) for sealing the two coupling parts (3, 5) and a locking mechanism (9) in order to couple together the two coupling parts (3, 5) in a releasable manner. The two coupling parts (3, 5) are equipped with valve arrangements (11, 13). Each of the two valves (11, 13)* comprises an axially displaceable valve (15, 17), with the valve (15) of the first valve arrangement (11) having an opening (150), in which a plunger (152) is mounted so as to move axially. In the state in which the coupling parts (3, 5) are coupled together, the plunger (152) keeps the two valves (15, 17) apart from each other. The plunger (152) can be locked by means of a catch device (110). The locking mechanism (9) is operatively connected to the catch device (110), so that, when the locking mechanism (9) is actuated for decoupling the two coupling parts (3, 5) that are coupled to each other, before disconnection of the coupling parts, the catch of the plunger (152) is released and the two valves (15, 17) are brought together with the respective valve seat (19, 21).
