Abstract
The present invention relates to a rail clamp for attaching a rail S comprising a central portion, at least one torsional portionbranching off laterally from the central portion, at least one transitional portionadjoining the torsional portionand at least one retaining armwhich is connected to the transitional portionand on the free end of which an end portionis configured, by which the rail clamp is supported on the foot F of the rail S 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 is achieved according to the invention in that the retaining armis continuously curved at least in a curve portion which extends up to the free end of its end portionsuch that, seen in a plan view of the rail clamp, the end portionis directed towards the central portionand the longitudinal axis of the torsional portionassociated with the respective retaining arm
