A cable tensioner includes two members, such as a pipe and a tube, that define a cable path. The members are helically mobile relative to each other. A retractable detent permits the relative movement of the members in one direction and prevents the relative movement of the members in another direction. The cable tensioner is thus irreversible, regardless of the operating conditions. The cable tensioner is, for example, applicable to a cable used in a vehicle window regulator. The window regulator cable extends in a protective sheath. One end of the protective sheath abuts against the second member, and the second member acts on the end of the protective sheath to increase the cable path and cable tension.
