An electrical connection element for a turbine engine, including conductors connected to a connector by a tubular coupling surrounding one end of the conductors, and an insert providing protection against wear of the conductors being mounted in the tubular coupling. The insert includes a substantially tubular central body containing the conductors and provided over at least a fraction of its length with a series of spacers bearing against an inside surface of the tubular coupling of the connection element so as to hold the central body at a distance from the inside surface.
