In a resilient railway rail fastening clip (9) comprising firstly a substantially straight first portion (1), then a bent second portion (2), then a substantially straight third portion (3) the axis of which makes an angle substantially more than 45° with the axis of the first portion (1), the two axes lying in the same plane as one another, then a fourth portion (4) which is a reverse bend, then a fifth portion (5), then a sixth portion (6) which is another reverse bend and finally a seventh portion (7), the first portion (1) is formed so as to comprise a region (1B) having a generally cylindrical surface extending along its entire length and a longitudinally-extending part (1A) having a surface which is less convex than the generally cylindrical surface region (1B) of the first portion (1). At least part of the second portion (2) and at least part of the third portion (3) are preferably manufactured with substantially flat surfaces (2A, 3A) on respective lateral regions thereof which contact the rail when the clip (9) is in use.
