Abstract[English] Device and method for holding a workpiece (1) during surface treatment of the workpiece (1) by using a fluid and/or a gaseous medium, the workpiece (1) comprising a treatable surface (2), a non-treatable surface (3) and an intermediate surface (10) in between of the treatable surface (2) and the non-treatable surface (3), the device comprising a covering component (7) for covering the non-treatable surface area (3) of the workpiece (1), said covering component (7) comprising a hollow chamber (8) and an opening (51) for receiving the non-treatable surface (3), wherein the covering component (7) comprising a sealing-acting surface (6) that is in contact with the intermediate surface (10) of the workpiece (1) when the non-treatable surface (3) is placed in the interior of the ho|low chamber (8), wherein the sealing-acting surface (6) of the covering component (7) is designed to fit the intermediate surface (10) of the workpiece (1) in such a manner that the interaction between the sealing-acting surface (6) and the intermediate surface (10) has a self-sealing effect, which results in sealing of the hollow chamber (8), so that penetration of the fluid and/or gaseous medium into the hollow chamber (8) is prevented, in this manner preventing contact of the fluid and/or gaseous medium with the non-treatable surface (3) of the workpiece (1) and allowing contact of the fluid and/or gaseous medium with the treatable surface (2) of the workpiece (1).[French] Dispositif et procédé de maintien d'une pièce (1) lors du traitement de surface de la pièce (1) à l'aide d'un fluide et/ou d'un agent gazeux, la pièce (1) comprenant une surface traitable (2), une surface non traitable (3) et une surface intermédiaire (10) entre la surface traitable (2) et la surface non traitable (3), le dispositif comprenant un élément de couverture (7) permettant de recouvrir la surface non traitable (3) de la pièce (1), ledit élément de couverture (7) comprenant une chambre creuse (8) et une ouverture (51) permettant de recevoir la surface non traitable (3). L'élément de couverture (7) comprend une surface agissant comme étanchéification (6) en contact avec la surface intermédiaire (10) de la pièce (1) lorsque la surface non traitable (3) est placée à l'intérieur de la chambre creuse (8); la surface agissant comme étanchéification (6) de l'élément de couverture (7) est conçue pour s'adapter à la surface intermédiaire (10) de la pièce (1) de telle manière que l'interaction entre la surface agissant comme étanchéification (6) et la surface intermédiaire (10) présente un effet auto-étanche, ce qui entraîne l'étanchéité de la chambre creuse (8) de sorte à empêcher la pénétration du fluide et/ou de l'agent gazeux dans la chambre creuse (8), ce qui empêche le contact du fluide et/ou de l'agent gazeux avec la surface non traitable (3) de la pièce (1) et permet le contact du fluide et/ou de l'agent gazeux avec la surface traitable (2) de la pièce (1).
