1. A connection element for electrically connecting an individual line which has a concentric conductor arrangement and a central channel for a cooling fluid, the connection element comprising:
a. an electrically conductive housing,
b. having a sleeve-shaped compression section which is suitable for producing a compression joint with the concentric conductor arrangement,
c. wherein the electrically conductive housing has an internal cooling channel having a connection opening for an external cooling line, said cooling channel leading into a space surrounded by the sleeve-shaped compression section,
d. wherein the connection element furthermore comprises a counterpressure element, which can lie at least partially in the space surrounded by the sleeve-shaped compression section,
e. wherein the counterpressure element is furthermore configured to support a concentric conductor arrangement on the inner side thereof when the sleeve-shaped compression section is compressed during the production of a compression joint, and is designed to be fluid-permeable in the pressed state in order to ensure a fluid connection through the counterpressure element.
