A tool for removing oil filter canisters or cartridges from an internal combustion engine, consists of a pair of elongate sidewalls that extend from the base of the tool along substantially the entire length of a canister or cartridge that is to be removed. The sidewalls of the tool are arranged to be drawn together by a cam and slot mechanism which is incorporated in the base of the tool and which is operated by an axially applied wrench. The sidewalls of the tool slant toward each other such that the distal ends of the sidewalls make primary, initial, gripping contact with the base of the canister or cartridge, with the inner surface of the sidewalls making secondary, gripping contact with a substantial portion of the sidewall of the canister or cartridge.
