Brake means (1) in linear movement devices comprising a drive means (3, 4), such as a piston which is reciprocatingly movable along the device (2). The brake means includes a bar (5) which extends parallel with the path of movement of the drive means and which accommodates a pressurizable hose-like element (10) that extends along the bar. The invention is characterized by a slat spring (17) accommodated in the bar and extending on one side of the hose-like element (10), a brake device (14, 16, 13) disposed along the slat spring (17) and movable transversely to the longitudinal direction of the hose-like element and the spring and located adjacent one longitudinally extending edge (18) of the spring, for movement transversely to said longitudinal direction and essentially in the plane of the spring (17) when the hose-like element (10) is placed under pressure and the spring is flexed outwardly. The brake means also includes a slide shoe (8) which is guided in the rail (4) and connected to the drive means (4) and actuatable by the brake device (14, 16, 13) that is movable towards the slide shoe (8).
