摘要

The device has a tubular connecting piece (22) releasably inserted into a filler neck of a fuel tank (10) in a motor vehicle. A protection device (20) is provided at the filler neck for preventing false refueling of the motor vehicle during refueling. The connecting piece includes a device (26) for increasing flow resistance of fuel flowing through the connecting piece. The flow resistance increasing device includes multiple elements that are arranged one behind the other in a direction of flow for increasing the flow resistance of the fuel.
