ABSTRACT:
An automotive type fuel tank-filler pipe connector consists of a one-piece flexible grommet having relatively rigid inserts embedded in the wall of the grommet and extending axially, the inserts comprising a number of flexible finger-like elements circumferentially separated but joined at one end by a chamfered nose portion, insertion of the grommet into a fuel tank opening being accomplished by the deformation of the nose portions being permitted by the radial inward collapsing of the fingers, passage of the nose portion past the tank opening returning the fingers outwardly; the insertion of the fill pipe camming the fingers further outwardly to clamp against the pipe, a further screw type hose clamp further clamping the grommet to the pipe.
