A cable-tightening device of the kind in which the cable is wedged between two parts which are clamped against each other when a tractive pull is applied in one direction on the cable, while the latter is free to slide through the device when the direction of the pull is reversed, comprising a tubular casing having a wall traversed by an oblique channel located in a radial plane and intended for the passage of the cable, and a cylindrical rotatable plug with longitudinal nipples mounted inside the tubular casing and elastically urged towards the cable-channel outlet, the longitudinal chamber formed inside the casing having a quadrilateral section and the diameter of the plug being slightly less than the dimension of the quadrilateral section in said radial plane. |
