A device (1) for the elastic stabilisation of bodies of the vertebra with A) at least two bone anchoring means (2), each of them having a central axis (3) and a head segment (4), and B) elastic means (5), which have a longitudinal axis (12) and can be joined with the head segments (4) of two adjacent bone anchoring means (2) in such a manner, that the longitudinal axis (12) extends transversely to the central axes (3), while C) under compressive load the elastic means (5) have a progressive spring characteristics (20), wherein D) the elastic means is manufactured from a metallic material, and E) comprise spring coils (19), of which at least two spring coils (19) have a geometric dimension which is different.
