RAIL CLAMP FOR ATTACHING A RAIL AND SYSTEM PROVIDED WITH A RAIL CLAMP OF THIS TYPE

A rail clamp for attaching a rail comprising a central portion, at least one torsional portion branching off laterally from the central portion, at least one transitional portion adjoining the torsional portion and at least one retaining arm which is connected to the transitional portion and on the free end of which an end portion is configured, by which the rail clamp is supported on the foot of the rail to be attached in each case during use, and relates to a system provided with a rail clamp of this type. The rail clamp and the system according to the invention are able, with a high endurance strength, to apply significant hold-down forces and at the same time to ensure that even during progressive wear of the rail attachment, adequately high hold-down forces continue to act on the rail. This can be achieved according to an embodiment in that the retaining arm is continuously curved at least in a curve portion which extends up to the free end of its end portion such that, seen in a plan view of the rail clamp the end portion is directed towards the central portion and the longitudinal axis of the torsional portion associated with the respective retaining arm. La présente invention concerne une pince de serrage destinée à fixer un rail S, présentant une partie centrale (3), au moins une partie de torsion (9, 10) partant de la partie centrale (3) dans la direction latérale, au moins une partie de transition (11, 12) raccordée à la partie de torsion (9, 10) et dotée d'au moins un bras de retenue (13, 14) raccordé à la partie de transition (11, 12) et sur l'extrémité libre de laquelle est réalisée une partie d'extrémité (19, 20).
