The paired legs (5,105,106) extending from the sides of the clamp are received in fitting recesses (8,108) in an edge rail (9,109). The distance (A,CA) between an end part (10,110) of the clamp working in conjunction with the piston and the centre (11,111) for the nearest located leg pair (5,105) is the same as for the clamp (2,102) which has one or two leg pairs. The centre for the stirrup-shaped part enclosing the piston connecting rod is located on a common line extending between the first leg pair (5) in a clamp which has one leg pair and centrally between the first and second leg pairs in a clamp which has two leg pairs. The clamp is prevented from rotating around its symmetry axis (7,107) when the piston (14) and the piston connecting rod (15) are loaded. |
