Abstract: A device for plug-connecting first and second electric lines includes a plug element assigned to the first line and having a plug pin. A socket element is assigned to the second line and receives the plug pin in a pin receiver for electrically contact. The socket element has a metal strip forming the second line. On its end facing the plug pin, the metal strip is deformed in a transversal manner with regard to its longitudinal direction while forming the plug receiver. The metal strip is deformed so that the plug pin can be inserted into the plug receiver in a longitudinal direction of the metal strip. Also, the metal strip forms a one-piece plate bar located external to the socket element. Electrical and/or electronic components are applied to the plate bar, and are electrically connected in an at least partial manner to the metal strip.
