A filler neck for the fuel tank of a motor vehicle, comprising a flap and a locking element. The filler neck is designed such that it is impossible to fill the tank with the wrong fuel. The foregoing is achieved by the fact that the flap can be rotated about a hinge pin which is three-dimensionally movable and while the flap is retained by at least two elements that are pivotable about one respective pin. One of the pivotable elements supports the hinge pin of the flap while another pivotable element is configured as a locking lever that is disposed across from the hinge pin.

Filler tube for the fuel tank of a motor vehicle with selective opening

A filling pipe for a fuel tank comprises a housing which has, on its inner circumference, a number of inwardly directed threaded segments and at least one vertical indentation, the upper part of the housing has segmented threaded parts for screwing a closure cap therein, and its lower part, which is contracted to the diameter of the filling pipe, contains an insert. The insert has, on its outer circumference, a number of outwardly directed threaded segments and two outwardly directed lugs, the segments together with the inwardly directed threaded segments of the housing holding the insert in the longitudinal direction, and the lugs together with the at least one indentation form a safeguard against twisting.
