The invention relates to an electric connector terminal for guiding a circuit through a wall (1), having a first terminal (2) to be mounted at a side of the wall and a second terminal (3) to be mounted at the other side of the wall (1), with the first terminal (2) comprising a connector element (4) to connect to the second terminal (3), the connector element (4) can be inserted into the second terminal (3), the second terminal (3) comprising a power line (6) for the electric connection to the first terminal (2), the power line (6) can be inserted into the connector element (4), and the surface of the connector element (4) facing away from the power line (6) comprising a creepage power extension (10). The creepage power extension (10) according to the invention increases the creepage distance, so that the electric connector terminal according to the invention can be impinged with higher voltages.
