Device for supporting a part

A device for supporting a part, comprising a mounting element having a wall mountable on a surface and having a pocket-shaped receptacle;

• and a suction element which supports the part and can be received in the pocket-shaped receptacle of the mounting element mountable to the surface or can be removed from the pocket-shaped receptacle of the mounting element and directly attached to the surface, so that in both cases the part is supported on the surface, either through the suction element and the mounting element or through the suction element only, wherein a width of at least one portion of the suction element is smaller than a width of the pocket-shaped receptacle of the mounting element, so that when the at least one portion of the suction element is inserted into the pocket-shaped receptacle of the mounting element, it is compressed and thereby tightly retained in the pocket-shaped receptacle of the mounting element, wherein the suction element has another portion which extends through an opening of the part, is flexible, and has a thickness that is greater than a size of the opening of the part, so that the another portion can be pushed through the opening with reduction of its thickness and then expanded behind the part after passing through the opening to reliably hold the part on the suction element, and wherein the at least one portion and the another portion of the suction element are flexible and compressible and together form the suction element as a one piece element composed of a same material.
