A line rupture safeguard for a hydraulic cylinder that has a connecting line between a connection for the hydraulic cylinder and a connection for a hydraulic unit, wherein a spring-biased closure unit in the connecting line is biased in a position releasing the connecting line, and at least partially closes the connecting line when a pressure differential in the connecting line is exceeded. A movable cam follower is provided that has a curved section which interacts with the spring-biased closure unit, and whose position dictates the spring bias of the closure unit and the pressure differential for at least partially closing the closure unit.
