PCT No. PCT/FR93/00196 Sec. 371 Date Sep. 30, 1994 Sec. 102(e) Date Sep. 30, 1994 PCT Filed Feb. 26, 1993 PCT Pub. No. WO93/19817 PCT Pub. Date Oct. 14, 1993The invention is related to a golf club head including a hollow body made of a single molded thermoplastic piece, an opening facing forwardly and including an upper wall, a peripheral wall, and possibly a lower wall. Further included is an impact-resistant metallic sealing element including a front wall forming the impact surface of the club head, attached and cooperating with the body so as to define an inner space. Such a construction improves upon the sensation perceived by the golfer at impact while retaining direct transmission of information to him or her, and it increases the range of possible mass distribution and concentration so as to make the head more tolerant by increasing its moments of inertia.
