1. Connection arrangement comprising:
a metallic flat conductor having an at least quadrangular cross-sectional profile and at least two opposing first and second surfaces extending at least partially parallel to one another in the longitudinal direction; and
at least two connecting lugs, which rest on the first surface with an overlap and project beyond at least one edge of the flat conductor,
wherein a metallic friction stir weld joint zone is formed extending from the second surface through the flat conductor to the first surface and projecting into the connection lugs, and
wherein the friction stir weld joint zone is formed from material of the flat conductor and of the connection lugs which has been plasticized during a joining operation.
