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 tension spring for holding down a track body element, comprising:
- a U-shaped main section which has a U-bend, a first leg being arranged on one side of the U-bend and a second leg being arranged on the other side of the U-bend;
- wherein a hook-shaped inwardly bent holding section configured to 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 is configured to be applied to the track body element via a bent end section;
- wherein the holding section has a free end portion connected to the first leg via a hook bend and arranged between the first leg and the second leg;
- and
- wherein the free end portion of the holding section, as viewed in the direction of a longitudinal extension of the free end portion, covers the U-bend at least partially.
A rail fastening device comprising:
- a tension spring for holding down a track body element, the tension spring comprising:
- a U-shaped main section which has a U-bend, a first leg being arranged on one side of the U-bend and a second leg being arranged on the other side of the U-bend;
- wherein a hook-shaped inwardly bent holding section configured to 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 is configured to be applied to the track body element via a bent end section;
- wherein the holding section has a free end portion connected to the first leg via a hook bend and arranged between the first leg and the second leg;
- and
- wherein the free end portion of the holding section, as viewed in the direction of a longitudinal extension of the free end portion, covers the U-bend at least partially;
- and
- a hold-down device configured to be fastened adjacent to a rail on a base, a ribbed plate, or an angle guide plate, and against which the holding section is braced in a mounted state of the tension spring so that the bent end section is configured to be arranged resiliently holding down a track body element.
