Abstract

A closure for a tank, in particular a fuel tank for a motor vehicle or the like, that has a tank filling pipe which can be closed with a closure flap, is described. The closure flap has a locking device with which it can be locked and unlocked and is also connected by a hinge or the like, so that it can move into the interior of the tank filling pipe. The locking device is located completely beneath the closure flap so that the closure flap can be locked and unlocked. Thus the locking device is not accessible from the outside, so it cannot be damaged or operated by an unauthorized party. The tank filling pipe can also be sealed airtight by the closure flap or by a closure valve arranged in the tank filling pipe.
