A terminal (3a . . . 3h) for the electrical connection of a plurality of electrochemical cells (2) of a accumulator, which terminal comprises a U-shaped outer rail (4a . . . 4f) and an actuating element (5a . . . 5g), is described. According to the invention, the actuating element (5a . . . 5g) is coupled to a clamping element (6a . . . 6f . . . 6h) in such a way that the clamping element (6a . . . 6f . . . 6h) is pressed against at least one limb (4a′ . . . 4f′) of the outer rail (4a . . . 4f) on actuation of the actuating element (5a . . . 5g).
