Abstract: The invention concerns a method and device for sliding and positioning sleeve-shaped elastic radially expandable components (8), made of a highly elastic material, without exerting great force, on cylindrical or conical base bodies (10) having an outer diameter which is greater than the inner diameter of these sleeve-shaped components (8), such as e.g. parts of a cable fitting set mounted and positioned on a cable end prepared in a manner known per se for a cable terminal or cable connection. Immediately before the component is placed onto the base body (10), a plurality of elongated, thin, flexible rib-like sliding tongues (2) in spaced-apart circumferential disposition is inserted in the cavity of the component (8) which has an approximately circular cross section. The sliding tongues (2) are inserted at slight lateral spacing from one another. On these sliding tongues (2) the expanding component (8) is pushed slidingly onto the base body (10) with only slight exertion of force.
