<p>The apparatus has a remote triggering module (5) that is guided and positioned in a case. The triggering module is connected electrically to a control line by flexible conducting blades (10). The flexible conducting blades are elastically deformed with respect to a contact terminal that is connected to a connection device and a fixed contact. The flexible conducting blades are maintained mechanically by a clip and a structure of the case. The triggering module includes an actuator for operating a mechanical lock if the control line conveys an opening signal.</p>
