Claim:
An assembly comprising: a sleeper; and fixing means for fixing a railway line to the sleeper, the fixing means comprising: (a) an elastic rail clip comprising a first clip bow, a second clip bow, a pressure bow, a first spring loop having a first end and having a third end, a second spring loop having a second end and having a fourth end, and a rotational axis; and (b) a clip anchor element comprising a guide ring having an annular outer guide slot; wherein the clip anchor element is positively held on the sleeper; wherein the first clip bow and the second clip bow can be inserted in the clip anchor element in order to be rotatably guided about and in the rotational axis; wherein the annular outer guide slot of the clip anchor element is concentric towards the rotational axis of the elastic rail clip when the first and second clip bows are inserted in the clip anchor element; wherein the first clip bow and the second clip bow are shaped substantially in an annular manner and are located in a guide plane; wherein the pressure bow is bow-shaped; wherein the pressure bow can have pre-tensioned contact with a rail foot of the railway line when the elastic rail clip is rotated relative to the clip anchor element about the rotational axis in order to fix the railway line to the sleeper or to a stretch of track; wherein the third end of the first spring loop connects the first spring loop to the pressure bow; wherein the fourth end of the second spring loop connects the second spring loop to the pressure bow; wherein the first end of the first spring loop connects the first spring loop to the first clip bow forming a first upright bow at the first end of the first spring loop; wherein the second end of the second spring loop connects the second spring loop to the second clip bow forming a second upright bow at the second end of the second spring loop; wherein each of the first upright bow and the second upright bow runs approximately vertically to the guide plane; and wherein the third end of the first spring loop and the fourth end of the second spring loop are guided through between the guide plane and the first end of the spring loop and between the guide plane and the second end of the second spring loop, respectively.
