Abstract
The invention concerns a device in fuel tanks, preferably for vehicles, said tanks being provided with a mouth socket to which a filler tube is connected so as to have its one end portion projecting into the tank. Between the mouth socket and the filler tube a seal is provided, the latter being formed with a portion grippingly enclosing the mouth edge of the socket and defining, together with the filler tube, an intermediate space allowing oscillation of the filler tube relatively to the socket. A washer is pressed against the filler tube and is formed with a bent-over portion grippingly engaging said portion of the seal. A reinforcement sleeve is positioned inside the filler tube and presses against the inner face of the filler tube. A clamp-joint sleeve is fitted around the mouth socket, enclosing portion of the seal and the washer.
