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 (9), then the angle (alpha) incline to bole's (6) portrait setting.
