A vent plug, for use in an electric storage battery, comprising a generally cylindrical component (16) for introduction through the lid of a battery in use, the cylindrical component being open at its opposite axial ends so as to provide a path for gas to flow therethrough from the interior of the battery to atmosphere, and, a baffle arrangement (23) within said cylindrical component (16), said cylindrical component (16) including a region (17) moulded as two semi-cylindrical elements (19, 21) united along one axially extending edge by an integral flexible hinge (22), said elements (19, 21) including mating latch components (24, 25; 24a, 25a) for holding the elements in a closed position relative to one another defining said region (17) of said cylindrical component and, said baffle arrangement (23) being moulded integrally with said region (17) of said cylindrical component so as to define a labyrinthine gas flow path through said region when said elements (19, 21) are latched together to define said region. <IMAGE> |
