ABSTRACT:
In a sealing cap for fuel tank pipes of motor vehicles with an outer cap (10) and an inner cover portion (12), the outer cap (10) has, at its inner side, a rib (36), made of synthetic material, which bears at least one radial lug (38) at its open end to serve as connection with the inner cover portion (12). In order to obtain a secure, torsion-proof connection between the outer cap (10) and the inner cover portion (12) during normal use and in order to facilitate a snapping off of the outer cap (10) in the case of motor vehicle accidents, the strength of the lug (38) is calculated to be low, and the torsion-proof connection between the outer cap (10) and the inner cover portion (12) is achieved by a separate positive-locking coupling (56, 58).
