An electrical connector provided with at least one male or female plug configured to be connected to a socket. The electrical connector includes at least one locking system provided with a polarized ferromagnetic locking element and with a return element, which are configured to have a first shape corresponding to a locking configuration of the electrical connector that is at least partially complementary to a shape of the connection plug or of the socket when an intensity of a current flowing through the connection plug is higher than or equal to a predetermined value, and a second shape corresponding to a non-locking configuration of the electrical connector when the intensity of the current flowing through the connection plug is lower than the predetermined value, so as to electromechanically lock the connection plug in the socket of the connector.
