(54)	Improvements relating to rail clamps

(57) A device (40) for securing a rail (10) relative to a rail chair (14) for inhibiting creep of the rail through the chair comprises first and second members (42, 44) which cooperate to grip the rail. The second member (42) is a C-shaped member the free end of which grip over upper surfaces of lower flanges of the rail. The first member (44) has a wedge-shaped end portion which engages between the C-shaped member and the rail. The other end of the first member (44) abuts the rail chair such that any tendency of the rail to creep in one direction increases the frictional engagement between the C-shaped member and the wedge-shaped portion.
