An elongated sleeve for anti-corrosion and decoration includes: a sleeve member having a socket formed therein; and an anti-corrosion lining member ratchetedly or irreversibly fixed in the socket of the sleeve member and operatively engaged with a wheel nut or a lug bolt secured on a wheel disk or cover, to thereby prevent corrosion between the sleeve member and the wheel nut or bolt as packed by the lining member between the nut or bolt and the sleeve member.
