A cover for a storage battery, comprising a main closure element (1) with charging holes (33), a secondary closure element (4) mounted on the main element, and a conduit (52), arranged for discharging the gases generated inside the battery case. The main element and secondary element together form a box-like structure (3, 4) defining a chamber (6) in flow communication with the holes, and inside which a labyrinth is defined which connects the holes of the main element to the gas discharge conduit. The chamber (6) is subdivided into a plurality of sub-chambers (6a, 6b, 6c), which are individually in flow communication with a collecting channel (41) which communicates with the gas discharge conduit (52). The collecting channel (41) comprises a first and a second longitudinal channel portion (41a, 41b), which extend along opposite sides of the chamber, and a transverse channel portion (41c) which extends along the centre line of the chamber and interconnects the first and second longitudinal channel portions. |
