The disclosure relates to an electrical connection between two busbars made of flat conductors and an insulating layer disposed between the conductors at the opposite longitudinal edges of the two busbars. The two conductors of each busbar run parallel to each other at a distance on the longitudinal edge thereof, wherein a molded part made of electrically insulating material bridges the distances between the conductors of the two busbars. Electrically conductive contact elements, forced against each other but electrically insulated from each other, each contact one of the conductors of each busbar by means of structured contact surfaces and clamp the same between the element and the molded part, wherein the contact surfaces for the conductors of the two busbars including clamping protrusions running parallel to the longitudinal edges.
