A b s t r a c t In a device for fixing stock rails in railway switches, comprising a base plate for the stock rail and a sliding chair for the switch tongue mounted on said base plate and comprising an elongated spring element for pressing down the rail foot and preferably having the shape of a plate, the spring element can be introduced, preferably without tension, into a tunnel-shaped recess provided in the sliding chair and extending approximately in vertical relation to the stock rail. The upper edge of the tongue-shaped recess within the sliding chair extends, with the formation of a kink , in direction to the rail foot steeper in upward direction than in an area extending more flat in front of the kink , and a separate wedge can, for the purpose of guying the spring element against the rail foot, be driven in within the area of flatter extension of the upper edge at a distance from the kink of the upper edge. On account thereof, a progressive spring characteristic of the spring element can easily be adapted to the requirements.
