A battery holder, attached to the clip is provided with upper and lower lateral extensions having gripping means thereon in facing relationship. One of the lateral extensions is provided with a small diameter hole adapted to receive the positive electrical anode contact of the battery while the opposite lateral extension is provided with a spring adapted to bear against the flat negative electrical cathode.
