A device for enhancing a user's grasping capability, comprising: - a belt-like support configured to be tightly fitted about a part of said user's body, said belt-like support having a longitudinal axis, - an articulated gripping element having a plurality of phalanxes (131, 132, 133) serially connected to each other about respective joint axes parallel to one another, said phalanxes comprising a proximal phalanx, connected to said support, and a distal phalanx, said phalanxes (131, 132, 133) articulated to each other by articular joints; - a motor unit fixed to said support; - a winding drum connected to said motor unit between and configured to move from an actuation condition to a release condition, and vice-versa; - at least one tendon partially wound on said winding drum and partially extending through said phalanxes (131, 132, 133) and said articular joints, said tendon arranged in such a way that, if said tendon is pulled by said winding drum in said actuation condition, said phalanxes (131, 132, 133) rotate about respective articular joints and move said articulated gripping element from an extended position to a bow-shaped gripping position, causing a flexion/extension movement of said articulated gripping element; said articular joints configured in such a way that, if said tendon is released by said winding drum in said release condition, said phalanxes (131, 132, 133) rotate about respective articular joints and move said articulated gripping element from said bow-shaped gripping position to said extended position, characterized in that said proximal phalanx is configured to allow said articulated gripping element to rotate about a rotation axis orthogonal to said longitudinal axis of said belt-like support, in order to allow said articulated gripping element to be wound like a bracelet or a belt in a bow-shaped rest position about said part of said user's body when said winding drum is in said release condition, and in that a passive-lock mechanism is also provided, said passive-lock mechanism being configured for blocking said articulated gripping element in said bow-shaped rest position. - a belt-like support configured to be tightly fitted about a part of said user's body, said belt-like support having a longitudinal axis, - an articulated gripping element having a plurality of phalanxes (131, 132, 133) serially connected to each other about respective joint axes parallel to one another, said phalanxes comprising a proximal phalanx, connected to said support, and a distal phalanx, said phalanxes (131, 132, 133) articulated to each other by articular joints;
