Abstract
An anchoring device (1) anchors a clip (60) to a foundation (50) for a railway rail (66). It has a head part (2) formed with a horizontal passageway (4) which is wider than it is high. In an upstanding wall section (5) there is a recess (6) and this receives a projection (52) on an electrically insulating bushing (51) which fits in the head part (2). The bushing has a passageway (53) through it and this receives two legs (61) and (62) of an e-shaped clip, the cross-section of the passageway having the shape of an athletics race track. The device (1) has a tail part (3) with projections (22 and 23) above which the tail part is of cruciform cross-section, with vanes (26 and 28).
