Abstract
A resilient rail-fastening clip has a first straight portion (11) for locating the clip in a clip anchoring device (2) when the clip is in use, a second bent portion (12), a third heel portion (13), a fourth bend portion (14) and a fifth toe portion (15). When viewed such that lower most points of the first and fifth portions (11 and 15) of the clip lie in a horizontal plane, proceeding from the first portion (11), the second portion (12) appears to bend up out of that plane towards and then away from a vertical plane passing through the fifth portion (15). The clip (1) is used in an assembly including a baseplate (2) having a non-vertical stop (21d) on its shoulder (21) up which the clip (1) slides during installation until brought to rest through friction at a desired height above the rail (3).
