<p>An arrangement for attaching a tank fitting to a plastics fuel tank for motor vehicles. Through an outwardly directed pipe stub in the tank wall the fitting is inserted and fastened to the tank. Between fitting and pipe stub an elastic sleeve is clamped whose inner end by means of an inner clamping means sealingly engages against the fitting, and whose outer end by means of an outer clamping means surrounds the pipe stub. The inner clamping means is part of a stiffening member bearing against the inside of the pipe stub by means of an upper support ring. The outer end of the sleeve is folded over outwardly and pressed sealingly against the pipe stub by means of the outer clamping means and aganist the reinforcing action of the stiffening member. The arrangement enables a simple and sealed attachment of heavy tank fittings, e.g. a fuel pump.</p> |
