Abstract
Seal in the cover of a storage cell for a malleable metal terminal post such as lead or indium terminal post provided with a blind hole opening towards the outside and a shoulder inside the storage cell. A flexible gasket is situated between the cover and the shoulder. An expandable rivet or the like is inserted in the blind hole and has a head that bears on the external face of the cover. Extraction of the rivet expands and shortens the terminal post and compresses the flexible gasket into sealing relationship between the shoulder and the cover without causing the expanded portion of the terminal post to come into contact with the cover thus avoiding danger of cracking the latter. Application is to small sealed lead storage cells.
