<p>The device (1) connects two rails (2) using two fish plates (4) held at fixed relative distance (a) by a bolt connection (3). Each fish plate has associated clamp elements (9), held in a roller aperture (7). Each element is moved by a pressure medium (11) from a first stop (12) nearer the bolt (6), to a second stop (13) away from it. The stops are connected by a contact surface (14) in the aperture to guide and support a clamp element.</p> |
