Abstract of the Disclosure A pipe-rupture safety device for natural-gas lines and the like, has a shut-off valve arranged in the natural-gas line. A monitoring device releases a signal in the event of a pressure drop in the natural gas line, and a control device controls the drive of the shut-off valve in accordance with the signal released. The drive is adapted to be acted upon directly by the pressure in the natural-gas line so that no external power source is required and the pressure of the natural-gas in itself actuates the drive ?o close the shut-off valve. The rupture safety device may be readily integrated with and arranged to act through the normally provided shut-off valve control system of the pipeline.
