1. A clamping device comprising:
a supporting base;
a pulley, operatively associable with a closure cable and comprising a winding surface for said closure cable, said pulley configured to rotate with respect to said supporting base about a first rotation axis, substantially perpendicular to said supporting base, according to a first winding direction or a second unwinding direction of said closure cable;
a handle coupled to said pulley and configured to be manually actuated to rotate said pulley;
first and second retainers, operatively engageable with a toothed surface of said pulley;
a control body, separate from said handle and operatively associated with said retainers, said control body comprising a control lever, which can rotate at least partially with respect to said supporting base about a rotation axis different from said first rotation axis and parallel to said first rotation axis;
said first retainer preventing said pulley from rotating according to said second direction when said control body is in a retaining position, said first and second retainers allowing said pulley to rotate freely according to said second direction, when said control body is actuated between said retaining position and a position of complete release, said first and second retainers allowing said pulley to rotate in a stepped manner according to said second direction, when said control body is actuated between said retaining position and a position of controlled release.
