Abstract

The invention is directed to a closure for a vessel such as a fuel tank or lubricant tank of a portable handheld work apparatus having an internal combustion engine. The closure includes a filling stub formed on the vessel and defining an opening and a cap for closing off the opening seal tight with respect to the ambient when the cap is placed on the filling stub. A holder prevents the cap from being separated from the vessel after the cap has been removed from the filling stub. The holder includes a flexible member having first and second end portions and an elongated flexible segment disposed between the end portions. A first attachment disposed on an inner wall surface of the cap fixedly holds the first end portion on the cap and a second attachment disposed on the vessel fixedly holds the second end portion on the vessel.
