Abstract
A corrosion-resistant tension member, particularly an inclined cable of a cable stayed bridge, is comprised of a bundle of individual elements, for example, steel wire strands, which in its open area is encapsulated by sheathing, and which within the structure extends inside a guide canal that is formed by a recess pipe. The sheathing--sealing off the front side of the guide canal--is thereby directly or indirectly connected to the structure. Between the sheathing and the entrance point of the tension member into the structure, a connecting pipe is arranged, which on the one hand is detachably connected to the sheathing and on the other hand is connected to the structure by a flange plate.
