A fuel cap for closing a filler neck of a fuel tank for a vehicle includes a cover pivotally supporting a handle for movement between an extended position and a retracted position. The cover encloses an outwardly extending flange portion of a threaded closure body. Ratchet teeth are formed on a wall of the cover opposite from the wall pivotally supporting the handle. The handle operably engages a surface of the flange portion for moving the ratchet teeth toward the opposite surface of the flange portion. The opposite surface of the flange portion includes corresponding ratchet teeth engageable with the ratchet teeth of the cover when the handle is in an extended position. A biasing member urges the intermeshing ratchet teeth toward a disengaged position when the handle is in the retracted position.
