A vented filling plug for an electric storage cell has a vent path including a flame trap through which gas may enter or leave the cell arranged so as, in use, to communicate with the interior of the cell at a point above the normal electrolyte level. The flame trap includes a liquid trap defined by a trough and a tubular partition, and a ceramic partition. The plug also has a filling path through which electrolyte may be poured into the cell arranged so as, in use, to communicate with the interior of the cell at a point below the normal electrolyte level. The filling path includes a liquid trap defined by a trough and a partition below the normal electrolyte level.
