A device having an integrated-circuit chip includes an insulating body containing at least one conductive pad, at least one electrical contact opposite the electrically conductive pad, and at least one recess in the body, including a bottom and one aperture. The recess is connected, at the bottom thereof, to the conductive pad and, at the aperture thereof, to the electrical contact. At least one coil spring is arranged in the recess and connecting the conductive pad to the electrical contact. The installation of the spring in the recess is facilitated by means of the friction of the central portion of the spring relative to the walls of the recess. The invention also relates to a method for producing an electrical connection between at least one conductive pad arranged in an insulating body and at least one electrical contact arranged opposite the electrically conductive pad.
