Zusammenfassung:A fastener (80) for attaching a first object to a second object comprising a shank (83) having a first portion extending from a first end of the fastener (80) provided with a thread in a first direction, a second portion adjacent the first portion, a third portion adjacent the second portion and extending to a second end of the fastener (80), a cylindrical cover (85) having an outer surface provided with a thread in the first direction and an inner substantially smooth surface, which is positioned over the third portion of the shank (83) and is moveably attached to the shank (83) to allow the cover (85) to spin around the shank (83) but not move lengthways along the shank (83), wherein the shank (83) and cover (85) are rotatable in a first rotational direction to threadedly engage the first portion of the shank (83) in the second object and to threadedly engage the cover (85) in the first object, to attach the first object to the second object with an inner surface of the first object adjacent an outer surface of the second object, and the shank (83) is rotatable in a second, opposite, rotational direction to partially threadedly disengage the first portion of the shank (83) from the second object, to move the second and third portions of the shank (83), the cover (85) attached to the shank (83) and the first object threadedly engaged with the cover (85) away from the second object to provide a gap between the inner surface of the first object and the outer surface of the second object, whilst maintaining attachment of the first object to the second object. A tool is provided for operation of the fastener. La présente invention concerne un élément de fixation (80) pour fixer un premier objet à un second objet comprenant une tige (83) ayant une première partie s'étendant à partir d'une première extrémité de l'élément de fixation (80) comportant un filetage dans un premier sens, une deuxième partie adjacente à la première partie, une troisième partie adjacente à la deuxième partie et s'étendant jusqu'à une seconde extrémité de l'élément de fixation (80), un couvercle cylindrique (85) ayant une surface externe comportant un filetage dans le premier sens et une surface interne sensiblement lisse, qui est positionné sur la troisième partie de la tige (83) et est fixé de manière mobile à la tige (83) pour permettre au couvercle (85) de tourner autour de la tige (83) mais pas de se déplacer dans le sens de la longueur le long de la tige (83), la tige (83) et le c
