Zusammenfassung:A termination of a tension member (1), for use as a tendon or tether for a tension leg platform. The tension member (1) consists of a plurality of carbon fibre filaments gathered into one or more strands (2) in which the filaments run against one another. A sheath (3) is provided around the strands. Each strand (2) is terminated in a receiving member (6) and the receiving member (6) is suspended in a recess (12) in a suspension member (7). The strands (1) are, over an area, spread out from a bundled strand to an arrangement of the individual filaments lying apart from each other. This spread-out area is held together by a protective cone (10) which prevents the spreading out from travelling down the strand. The individual carbon fibre filaments (2) are inserted into respective cavities (4) in a receiving member (3) and secured therein with a solidifying substance (5). The cavities in the receiving body (3) may be through-going, or they may be blind. Moreover, the cavities (4) may be of different configurations, from a hole of uniform diameter, an upward or downward facing conical cavity, or a gradually stepped cavity. By securing the carbon fibre filaments in this way, a good anchoring of each individual filament is ensured, as well as a longitudinal adjustment of the filaments, which gives a uniformly distributed load over the strand (1), and that in the main only axial forces are applied to the individual carbon fibre filaments (2). L'invention concerne une terminaison pour élément de tension (1), à utiliser comme un câble de précontrainte ou d'attache pour une plateforme à câbles tendus. L'élément de tension (1) consiste en plusieurs filaments en fibre de carbone groupés sous forme d'un ou plusieurs faisceaux (2) de filaments s'étendant les uns contre les autres. Une gaine (3) est prévue autour des faisceaux. Chaque faisceau (2) se termine dans un élément de réception (6), lequel est suspendu dans un évidement (12) prévu dans un élément de suspension (7). Les faisceaux (1) sont, sur une certaine zone, divisés pour former un ensemble de filaments séparés les uns des autres. Cette zone de division est maintenue par un cône de protection (10) qui empêche la division de descendre vers le faisceau. Les filaments en fibre de carbone séparés (2) sont insérés dans des cavités respectives (4) d'un élément de réception (3) et sont fixés dans ces dernières à l'aide d'une substance solidifiante (5). Les cavités du corps de réception (3) peuvent être traversantes ou
