Abstract
The invention is directed to a threaded closure for a fuel tank and includes a thread formed on a fuel inlet stub of the tank. A closure cap has a thread for engaging the thread on the inlet stub. A latch member is arranged on the closure cap and includes a peripheral ring which is mounted on the base body of the closure cap so as to be axially journalled thereon for movement between an unlatched position whereat a handle of the peripheral ring projects beyond the upper surface of the base body to facilitate manually grasping the closure cap and for providing a visual indication that the latch member is in the unlatched position. The peripheral ring includes a toothing formed on the inner wall surface thereof for engaging the toothing formed on the outer wall surface of the inlet stub when the latch member is in the latched position thereby preventing an unintended rotation of the closure cap. Also, in the latched position, the handle is recessed in a recess formed in the base body of the cap.
