The pulley comprises a securing head and a first flange. A first shaft extends from the first flange. A second flange and a sheave are mounted rotatable around the first shaft with respect to the first flange. A rod is fixed to the first flange and mounted movable between a first position and a second position with a first movement. In the first position, the rod engages with the second flange to keep the second flange in the first position. In the second position, the rod allows rotation of the second flange. A blanking plate is fixed on the second flange and mounted movable between a first position and a second position with a second movement different from the first movement. The blanking plate partially covers the rod to prevent movement of the rod from the first position to the second position.
