    • 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.
    • 在弹性的铁路轨道紧固夹(9)中,首先包括基本上直的第一部分(1),然后是弯曲的第二部分(2),然后是基本上直的第三部分(3),其轴线基本上大于45° °与第一部分(1)的轴线相同,两个轴彼此相同的平面,然后是第四部分(4),其是反向弯曲的,然后是第五部分(5),然后是第六部分 6),其是另一个反向弯曲部分,最后是第七部分(7),第一部分(1)形成为包括具有沿其整个长度延伸的大致圆柱形表面的区域(1B)和纵向延伸部分 1A)具有比第一部分(1)的大致圆柱形表面区域(1B)更小的表面。 第二部分(2)的至少一部分和第三部分(3)的至少一部分优选地在夹子(9)处于其中的与其相接触的横向区域上具有基本平坦的表面(2A,3A) 使用。
