The device for securing people against a fall has a rail which is fastened by means of holders, and a runner which is guided along the rail. The rail is held movable in its longitudinal direction in the holders. The rail preferably has a closed hollow profile with roughly square cross-section and with flanges pointing away from each other on each of two opposite-facing side surfaces of the cross-section profile, the cross-section profile of the rail being symmetrical about the horizontal and the vertical axis. At least one end of the rail is preferably held in a path force limiter, which opposes a pre-set resistance to a movement of the rail.
