A device for fastening an object to an element (1) which, for fastening purposes only, has a hole (2) in a surface has two parts (5, 6) which are connected for pivoting relative to one another and each have their respective protrusion (10, 11) so arranged that in a first inactive rotational position of the parts they are close enough to one another to allow them to be inserted together in the hole and that when the parts are mutually pivoted to an active fastening position they are parted and grip from behind other surfaces (30) which surround the hole on the opposite side of the hole from the first-mentioned surface (3). Each part has a means (16, 19) so arranged that, when the parts are pivoted from the inactive position towards the active fastening position, it moves, relative to the insertion direction of the protrusions in a said hole, in the opposite direction to the protrusions in order to come to abut against the first-mentioned surface surrounding the hole on opposite sides of the hole and, upon continued pivoting, it presses against that surface and acts upon the protrusions in the direction outwards from the hole while they are being pressed apart. <IMAGE> |
