Abstract
A closure for a fuel tank filler pipe comprises a body carrying a seal at one end for engagement with an outer end of the filler pipe, an outer cover, and a latch member at the other end of the body coupled to the cover and having latching projections for engagement with complementary formations on the filler pipe. A spring biases the latch member towards the outer cover so as to urge the seal into engagement with the end of the filler pipe when the latching projections on the latch member are in engagement with the complementary formations on the filler pipe. The connection between the latch member and the outer cover allows a predetermined range of angular movement of the outer cover relative to the latch member in the unlocking direction before unlocking commences.
