In a railway rail fastening clip (10), for use on a railway rail baseplate (40) of the K-plate type, comprising an elongate member bent such that first and second end regions (11, 12) of the member form respective lower and upper limb portions, the lower limb portion (11) forming a base portion (19) of the clip (10) for engaging a slot (31) in the baseplate (40) and the upper limb portion (12) extending further than the lower limb portion to form at its free end a toe portion (15) of the clip (10) for bearing on a rail foot (65). The toe portion (15) is not bifurcated and the width of the toe portion (15) of the clip (10) is narrower than the width of the upper part (31a) of the slot (31) in the baseplate (40) whereas the width of the lower limb portion (11) of the clip (10) is broader than the width of the upper part (31a) of the slot (31) in the baseplate (40). The clip (10) is retained in the slot (31) by means of a device (20) comprising a plate portion (21) for location on the rail foot (65), the plate portion (21) being provided with an abutment surface (23') for abutting the toe portion (15) of the clip (10).
