1. A device for transferring a line between a retracted state and an extended state, comprising:
a line arranged in an interface region between a semitrailer train and a semitrailer, wherein the line has a first line section and a second line section and wherein the line is longer in the extended state than in the retracted state; and
an envelope element via which the first line section and the second line section are connectable for transfer between the retracted state and the extended state by forming a telescopic mechanism;
wherein the line comprises a gas pressure line where the first line section is guided in a gas-tight manner in the envelope element, and/or comprises an electrical line where a connector bushing element is in and maintains electrical contact with an electrically conductive part of the first line section in both a retracted state and an extended state.
