1. A fitting for a liquid gas bottle with a gas consumer connection piece, with a gas inlet opening on an underside, with a first gas conducting connection between the gas inlet opening and the gas consumer connection piece, with a rotary handle, which can be turned into an open position and into a closed position, wherein in the open position gas can flow from the gas inlet opening to the gas consumer connection piece and in the closed position no gas can flow from the gas inlet opening to the gas consumer connection piece, with a closable opening on an upper side of the fitting, with a second gas conducting connection which connects the closable opening on the upper side with an opening at the underside in such a way that refilling a connected liquid gas bottle with gas through the underside and through the closable opening is possible, and wherein an edge of the closable opening is part of the rotary handle, wherein the closable opening comprises a closure body on the upper side of the fitting, and wherein a stroke movement of an inner cylinder is limited by a sealing ring which extends into a recess which is wider than the sealing ring so that the sealing ring can be moved along the recess.
