A circuit for testing electric conductors connected to a socket with a protective contact for their correct connection, possessing two current pins, a contact sleeve and a touch electrode, and containing luminous elements, preferably containing resistors characterised in that one current pin (K1) is connected, with the use of the first diode (D1) and the first resistor (R1), to normally opened contact (A) of the connector (P) and to the contact sleeve (PE) with the use of the second diode (D2), the second resistor (R2) and the third diode (D3) connected in a parallel manner and the fourth diode (D4), and the second current pin (K2) is connected to the second normally opened contact (D) of the connector (P) and to the contact sleeve (PE) with the use of the fifth diode (D5), the third resistor (R3) and the sixth diode (D6) which is connected in a parallel manner and the seventh diode (D7), and the sleeve (PE) is also connected to the normally closed contact (F) of the connector (P), and, to the switchable contacts (B) and (E) of the connector (P), a neon lamp (N) is connected, and the second normally closed contact (C) of the connector (P) is connected to the touch electrode (M) with the use of the fourth resistor (R4).<IMAGE>
