Hydraulic operating system comprises a master cylinder unit (10), a slave cylinder unit (12), a hydraulic line (14) connecting the two cylinder units, and a throttle valve (26) for changing the flow resistance between the cylinders of the master and slave cylinder units. An Independent claim is also included for a device for connecting a tubular hydraulic line to a connection on a housing, especially in the above hydraulic system. Preferred Features: The throttle valve is operated by an actuator (18) controlled by a control device that is connected to a sensor determining the movement of a piston in at least one of the two cylinder units.
