Abstract: The present invention pertains to a holding device (4) for holding an electric fan (1), in particular, a minifan, on a mounting wall (2). The invention is characterized by at least one essentially flat holding part (10), one side of which defines a fan contact plane (12), wherein said holding part comprises at least one plug element (14) that projects from the holding part (10) approximately perpendicular to the contact plane (12) and can be positively and/or nonpositively inserted into a mounting hole (16) of the fan (1) as well as at least one pin-like fastening element (22) that projects from the holding part (10) approximately perpendicular to the plug element (14) and can be inserted into a hole (20) in the mounting wall (2).
