A brake for linear movement devices comprising a device. The brake means includes a bar which extends parallel with the path of movement of the device and which accommodates a pressurizable hose-like element that extends along the bar. The invention is characterized by a slat spring accommodated in the bar and extending on one side of the hose-like element, a brake disposed along the slat spring and movable transversely to the longitudinal direction of the hose-like element and the spring and located adjacent one longitudinally extending edge of the spring, for movement transversely to the longitudinal direction and essentially in the plane of the spring when the hose-like element is placed under pressure and the spring is flexed outwardly. The brake also includes a slide shoe which is guided in the rail and connected to the device and actuable by the brake device that is movable towards the slide shoe.
