The invention relates to fixing means for fixing railway lines to sleepers or stretches of track, comprising an elastic rail clip (51) and a clip anchor element (31). According to the invention, the elastic rail clip (51) has retaining elements that can be inserted into the clip anchor element (31) and guided into the latter by being rotated about a rotational axis (D) and at least one pressure bow (52), which can be brought into pre-tensioned contact with the foot (24) of a railway line (21), when the elastic rail clip is rotated (51) about the rotational axis (D) in relation to the clip anchor element (31). The elastic rail clip (51) has essentially annular clip bows (55, 56) that act as the retaining elements and the clip anchor element (31) has guide elements (34) that are concentric with the rotational axis (D).

L'invention concerne des moyens de fixation servant à fixer des rails de chemin de fer sur des traverses ou des voies ferrées et comprenant un crapaud élastique (51) et un ancrage de crapaud (31). Le crapaud élastique (51) présente des moyens de retenue qui peuvent être insérés dans l'ancrage de crapaud (31) afin d'être guidés dans cet ancrage en tournant autour d'un axe de rotation (D), ainsi qu'au moins un étrier de serrage (52) qui, lors de la rotation du crapaud élastique (51) autour de l'axe de rotation (D) par rapport à l'ancrage de crapaud (31), vient se placer en appui précontraint sur le patin (24) d'un rail (21). Le crapaud élastique (51) comprend, comme moyens de retenue, des clips pratiquement recourbés en anneau (55, 56) et l'ancrage de crapaud (31) présente des moyens de guidage (34) concentriques par rapport à l'axe de rotation (D).
