ABSTRACT:
A device to be used in inserting the individual tension elements of a freely tensioned tension member, for example, a stay cable for a cable-stayed bridge, into a tubular sheathing. A guide element to be attached to the front end of an individual element includes an expansion member whose diameter in its non-expanded state corresponds approximately to the diameter of the individual element, while the diameter in the expanded state is greater than the diameter of the individual element.
