Device for attaching an apparatus onto a panel

A device (100) for fastening a fitting to an attachment face (20), of a panel (1) comprising:

• at least one mortise (7) that passes through the panel (1) and opens out onto said attachment face (20), and an opposite face (30), that lies on the opposite side from the attachment face (20), the fastening device (100) having a longitudinal axis (118) and comprises:
• a clamping member (102) comprising a clamping jaw (105), which is shaped to pass through the mortise (7) translationally along the longitudinal axis (118) and to bear against the opposite face (30) following rotation about the longitudinal axis (118), and comprising a device (104) for attaching the fitting (101) to the attachment face (20);
• and
• a peg (108) for anchoring the fastening device (100) in the panel (1), said peg (108) rotating as one with the clamping member (102) about the longitudinal axis (118) of the fastening device (100) and comprising an anchoring jaw (109), which is designed to be able to bear against the attachment face (20);
• said clamping member (102) being designed to be able to be moved translationally with respect to the anchoring peg (108) along the longitudinal axis (118) between:
• a blocking position of the fastening device (100), in which the clamping jaw (105) and the anchoring jaw (109) have been moved toward one another by elastic return device (112) and are in contact with the two main faces of the panel (1);
• and
• an installation position of the fastening device (100), in which the clamping jaw (105) and the anchoring jaw (109) have been spaced apart from one another with respect to the blocking position so as to allow the fastening device (100) to rotate about the longitudinal axis (118).
