A coupling for connecting hydraulic pipelines has a first coupling part (1) and a second coupling part (2). The two coupling parts each include a valve (V1, V2, V3). A receiving part (4) is provided which is associated with the first coupling part (1). The receiving part (4) serves to receive the second coupling part (2). A locking sleeve (38) and a locking element (40) can be locked relative to the receiving part (4). To facilitate actuation of the locking sleeve (38) in the opening sense, a rotational play is provided between a switching member (23) to actuate the valve body (8) of the valve (V1) and the switching shaft (27) to actuate the switching member (23). The rotational play can be used for moving the locking sleeve (38) into the open position via an opening element (47) which is adjusted by an actuating element (48).
