The invention relates to a device for indicating that an electrode cable (2) is correctly connected to an implant (1) for emitting electrical pulses, the implant (1) by being equipped with a connection part (3) for the electrode cable's proximal end (11). The indication device contains a contact means (9) for electrically seating the proximal end (11) of the electrode cable and an indication means (10), the contact means (9) electrically causing the indication means (10) to emit at least one indication signal (18) which is perceptible outside the implant (1) when the electrode cable (2) is correctly attached to the implant (1).
