Date Dec. 27, 1996In a device for securing stock rails in railway switches comprising a bearing plate (2) for the stock rail (1), a slide chair (3) for the switch blade and an elongate spring element (6) for holding down the rail foot (1), the spring element (6) is insertable into a tunnel-shaped recess (5) of the slide chair (3) at a tension insufficient for holding down the rail foot (1), or without any tension at all, and is braceable relative to the rail foot (1) and the bearing plate (2) by a separate clamping wedge (10) extending transverse to the spring element (6). The spring element (6) has a cross section varying over its length and, starting from a central region in which it cooperates with the transverse wedge (10), tapers towards its two free ends and, on its free end (9) facing away from the rail foot (1), is designed to project towards the bearing plate (2).
