A device for the manual release of gate wings, comprises: two jaws (2) which are articulated at a pivot, said jaws being rigidly coupled to the movable wing (6) (to a bracket (12) which is articulated to the hinges of the gate); a bolt (8) which is accommodated in the bracket (12) (in the movable wing (6)) and can engage elastically between the jaws; elements (24,30) for actuating the two jaws between a position in which the jaws are locked, so as to keep the bolt head clamped, and a position in which the jaws can rotate freely, allowing the disengagement of the head of the bolt. <IMAGE> |
