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, then a second reverse bend portion (12), then a third portion (13), then a fourth reverse bend portion (14) and finally a fifth portion (15). When viewed such that lowermost points of the said first and fifth (11 and 15) portions of the clip lie in a horizontal plane (Y), proceeding from the said first portion (11), the said second portion (12) appears to bend up out of that plane towards and then away from a vertical plane (Z) passing through the said 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).

Un crapaud élastique d'assemblage de rails comporte une première partie droite (11) permettant de positionner le crapaud dans un dispositif (2) d'ancrage de crapaud lorsque ce crapaud est utilisé, une seconde partie coudée en U (12), une troisième partie (13), une quatrième partie coudée en U (14) et enfin une cinquième partie (15). Lorsque l'on regarde la seconde partie à partir de ladite première partie (11),de telle manière que les points les plus bas desdites première et cinquième parties (11 et 15) du crapaud se trouvent dans un plan horizontal (Y), ladite seconde partie (12) semble s'incurver vers le haut hors de ce plan pour se rapprocher puis s'éloigner d'un plan vertical (Z) passant à travers ladite cinquième partie (15). On utilise ce crapaud (1) à l'intérieur d'un ensemble comportant une plaque de base (2) pourvue d'une butée non verticale (21d) sur son épaulement (21), le crapaud (1) glissant sur cet épaulement lors de l'installation par frottement jusqu'à une position de repos, à une hauteur souhaitée au-dessus du rail (3).
