Abstract
A rail to tie fastening including an elastic clip (12) a clip holder (15) and a locking element (6). The locking element (6) being interposed between the foot of the rail (11) and the clip holder (15) and, between the foot of the rail (11) and the clip (12) and is forced by the clip (12) against the foot (11). The locking element (6) is so shaped that any movement of the locking element (6) parallel to the rail (11), induced by longitudinal movement of the rail (11), results in the locking element (6) wedging between the clip holder (15) and the foot of the rail (11) so increasing lateral pressure on the rail to prevent further longitudinal rail movement.
