1. A cover for an energy guide chain, wherein the cover comprises:
a first end region;
a second end region; and
an elastic section between the first end region and the second end region; wherein the cover has an initial length and a second length when subjected to tension to define an actual length change S, and wherein the following ratio applies:
ΔL/S<1
where ΔL is a length change of the cover with a length L0 due to a force according to Hooke's law, and S is the actual length change of the cover due to the force.
