A axial securing element 3 for fixing two workplaces in relation to each other consists of a ring 3 of rectangular cross- section having conical external surfaces set obliquely at an angle of less than 90 DEG to the engaging surfaces on the work pieces and designed to change their diameter so that they can be fitted into notches on the work pieces 1, 2 as shown in fig. 8. To enable them to take up exceptionally high axial forces, the ring is made up of at least two part-elements 3a, b, c (fig. 2) or 3d, 3e (fig. 8) which can be placed into position independently of each other but cooperate with each other. These part-elements may consist of ring segments (fig. 2) obtained by sub-dividing a ring at its circumference or they may consist of split part-rings of different mean diameters (fig. 8), with the internal and external contours so adjusted to each other that the part-rings fit into each other with the surfaces facing each other. <IMAGE> |
