The device (30) has first and second contact elements e.g. outer and inner flanges (31, 32), co-operating with a part of an outer surface (13) and a part of an inner surface (14) of a motor receiving caisson (10), respectively. A locking unit (35) is formed of a screw, a screw-nut assembly and a pivoting hook, and acts on the first and/or second contact elements in a direction of bringing the contact elements and the outer and inner surface parts of the receiving caisson, close together, respectively. |
