Abstract: In a plug-in connector (1), at least one part of the busbar element (10) is in each case arranged in the boundary area between an associated conductor entry opening (3) and an associated contact pin receiving opening (8) in such a manner that the part of the busbar element (10) is located between a contact pin (14) and an electric conductor (5) and electrically conductively rests against the contact pin (14) and the electric conductor (5). The busbar element (10) has a resilient contact area in the contact pin receiving opening (8) for electrically contacting the busbar element (10) by a spring force with a contact pin (14) which can be inserted into an associated contact pin receiving opening (8).
