ABSTRACT:
A device comprises two jaws arranged to be pressed one against the other and to grasp a part to be positioned and secured. The part and/or the jaws comprise circular regions presenting a succession of planar or curved facets regularly disposed over said regions, with adjacent facets forming obtuse angles between them whose vertices define sharp edges or points. In a preferred embodiment, the jaws clamping a part having a rounded portion are tightened by means of two screws whose centerlines form an angle with each other, so that upon tightening of the jaws, at least one of the jaws flexes so as to assure a better grip of the rounded portion of the part.
