A high-current (HC) plug-in connector for currents exceeding 100 A, in particular 200 A, is provided. The high-current (HC) plug-in connector may include a first connecting element having a first contact section, and a second connecting element having a second contact section. Furthermore, a spring element is provided for establishing an electrical connection between the first and the second connecting element. The spring element may include at least two clamping elements which are interconnected via at least one web, the web and respective first sections of the clamping elements being arranged on a first outer surface of the connection formed by the first and the second contact section, and second sections of the clamping elements being arranged at least in part on a second outer surface opposite the first outer surface. At least one contact spring is arranged on the at least one web, the at least one contact spring generating, on the first outer surface, a contact force oriented in the direction of the second outer surface, whereby mutually facing contact surfaces of the first and the second contact section are pressed against each other, the second sections of the clamping elements serving as abutments.
