Abstract (en)

[origin: EP0455236A1] What is proposed is a rail fastener by means of which a rail (12), which is essentially fixed in position on a support (10), can be displaced in the longitudinal direction. For this purpose, first and second parts (26, 28) emerge from the support and the rail which can be displaced relative to one another in the longitudinal direction of the rail. <IMAGE>
