ABSTRACT:
A closure for the filler pipe of a tank, comprises a gasket mounted in a gasket housing and arranged to engage with a flange on an end of a filler pipe, a cap stem coupled to the gasket housing for relative angular movement about the axis of the filler pipe and having a central portion adapted to project into the filler pipe. A clamp ring carries a pair of clamping lugs adapted to pass through cut-outs in the flange and, after angular movement, to engage under the flange. A spring acts between the stem and the clamp ring to urge the clamping lugs into engagement with the flange. A cam acts between the clamp ring and the gasket housing to hold the clamping lugs out of engagement with the flange until the clamp ring is at a predetermined orientation relative to the gasket housing. A locking ring couples the stem to the clamp ring. The cam is so arranged that, when the clamp ring is in the above-mentioned predetermined orientation relative to the gasket housing, the locking ring disengages the stem from the clamp ring so as to permit relative angular movement and a second cam formation on the locking ring engages with a complementary surface on the clamp ring to wedge the clamping lugs in engagement with the flange.
