Abstract: A tensioning device includes a circular spring, and a pulley rotatably connected to the circular spring. The pulley includes a circumferential groove, which has a V-shaped cross-section defined by two lateral converging walls. The pulley also includes a flexible rope having a variable cross section, extending between a first end connected to the pulley and a second end intended to be connected to the cable. The pulley is rotatably movable around an axis, between a first position in which the flexible rope is arranged in the circumferential groove around the axis, and a second position in which the flexible rope is unwound.
