An electrical interconnection system for electrochemical generators including electrodes and connection members providing continuity of electrical current flow from the electrodes to the exterior of said generators connects the electrodes to the connection members and the connection members to each other by means of a mechanical and electrical joint. In an area in which there is initially a substantially plane contact surface between the parts to be joined, the joint is in the form of a plastic deformation of the parts to be joined and is situated at a sufficient distance from the edges of the parts for the edges not to be deformed. The plastic deformation consists in cold flow of the material of the parts in parallel directions in the same sense which immobilizes the parts relative to each other, only the parts contributing to the joint and being in intimate contact throughout the area subject to deformation.
