A sealed galvanic cell has a tubular casing (11) sealed at one end with a plastics closure member (13) covered by an outer conducting cap (15). The closure member (13) is moulded with an integral plug (26) joined to the remainder of the closure member by a thin plastics web (25) extending along the length of the tube and capable of rupturing and thereby releasing the plug (26) in the event of excess gas pressure in the cell. <IMAGE> |
