Abstract

The invention relates to a tension clamp for the holding of a rail for rail vehicles and a rail fastening point. The tension clamp has a central section having two legs, two torsional sections connected thereto and leading away laterally in an outwards direction having a supporting zone, and two supporting arms connected to the torsional sections. The supporting arms run to the front face of the tension clamp and have a spring section and a support section with a supporting zone. The fact that the support sections point laterally in an outwards direction such that the straight lines which in each case connect the centers of the supporting zones and the torsional section allocated to the supporting arm in an area on the rear face of the tension element increases the natural frequencies of the tension clamp such that they are outside of stimulation frequencies that occur in practice.
