The invention relates to a wall feedthrough, in particular for a metal wall and for a high-voltage coaxial cable, said feedthrough comprising an insulating socket which is affixed to the wall and which includes a central segment, an upstream end and a downstream end, said ends each projecting on its side from the wall. The insulating socket allows passing a cable inner conductor through it, and the feedthrough furthermore includes primary mechanical fasteners at the downstream socket end which cooperate with secondary mechanical fasteners affixed to the sheathed part of the cable. This feedthrough is characterized in that the cable's inner conductor is electrically insulated from the wall by pre-stressed electric insulators.
