Abstract
A tension spring for holding down a track body element, such as a rail foot of a rail, including a U-shaped main section which has a U-bend, a first leg arranged on one side of the U-bend and a second leg arranged on the other side of the U-bend, wherein a hook-shaped inwardly bent holding section which can be braced against a hold-down device is formed on the first leg and an end section bent towards or away from the holding section is formed on the second leg, wherein the U-bend forms a torsion section so that a hold-down force can be applied to the track body element via the bent end section.

A rail fastening device comprising:
- a tension spring configured to hold down a track body element;
- and
- a hold-down device configured to be fastened adjacent to a rail on a base;
- wherein the tension spring comprises a U-shaped main section having a U-bend, a first leg arranged on one side of the U-bend and a second leg arranged on the other side of the U-bend;
- wherein a hook-shaped inwardly bent holding section which can be braced against the hold-down device is formed on the first leg and an end section bent towards or away from the holding section is formed on the second leg;
- wherein the U-bend forms a torsion section so that a holding-down force can be applied to the track body element via the bent end section;
- and
- wherein the holding section is supported on the hold-down device in the mounted state of the tension spring so that the bent end section can be arranged to resiliently hold down the track body element when installed transversely to a longitudinal direction of the rail.
