Abstract

L'invention concerne un dispositif de fixation, en particulier pour des revêtements (2) plans et/ou à parois minces à monter et/ou à visser sur un élément de fixation complémentaire (4) du type axe, lequel traverse un évidement (3) du revêtement (2). Le dispositif est pourvu d'au moins - un élément d'accrochage (6) pour l'accrochage ou l'agrippement du dispositif de fixation (1) à l'élément de fixation complémentaire (4) et d'au moins - un élément de transmission (7) pour la transmission d'une force de retenue (FH) agissant dans la direction longitudinale (L) de l'axe sur le revêtement (2). Le dispositif de fixation (1), aux fins de pré-assemblage du dispositif de fixation (1) sur le revêtement (2), possède des moyens pour retenir le dispositif de fixation dans la zone d'un évidement (3) du revêtement (2), les moyens comportant au moins deux éléments jointifs, lesquels font saillie de l'élément de transmission (7), et sont en particulier formés d'une seule pièce sur celui-ci, afin de traverser l'évidement (3) dans le revêtement (2).
