A locking cap for an oil gauge pipe which includes a gauge rod mounted thereon, with the gauge rod being adapted to be inserted into the oil gauge pipe. An eccentric level arrangement is provided for locking the locking cap at the oil gauge pipe while a sealing ring is pressed between the locking cap and a flange of the oil gauge pipe. The eccentric lever is mounted on the locking cap and, in a locking position, reaches under the flange of the oil gauge pipe. In a locked position, the locking cap rests against the flange with the sealing ring being interposed between an inner surface of the locking cap and the flange.
