Abstract: An arrangement for positioning components such as die or mold plates in shaping machinery, in which a positioning element is inserted into matching bores in the components to be positioned. The positioning element or device is provided with a cylindrical jacket around an axial bore and a continuous through-going slot. An elastic rod is inserted into the axial bore and is subjected to force from at least one end, for the purpose of increasing the thickness of the elastic rod and widening the cylindrical jacket so as to position the component. The components have, thereby, an elastic connection through the elastic rod. The continuous through-running slot provides elasticity by widening in accordance with the force that is applied.
