ABSTRACT:
An electric cell has a terminal post of which one end is of reduced diameter and passes through a hole formed in a wall of the cell and at least a part of which is screw threaded and carries a nut. The terminal post has a shoulder which is drawn by the nut towards the inner side of the wall. Between the shoulder and the wall is a cup washer having a recess which engages a projection carried by the wall. A locking washer is interposed between the cup washer and the shoulder so that rotation of the terminal post is prevented.
