Abstract

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).
