Abstract

An attachment organ (1) for coupling a tool (100) to an operating arm (110), comprising: a frame (9), which exhibits a first transversal seating (2) and a second transversal seating (3) which are respectively predisposed for housing a first attachment pin (101) and a second attachment pin (102) of the tool (100); a locking hook (4) which is mobile with respect to the frame (9) and means for moving (10) the locking hook (4), the locking hook (4) being predisposed for closing on the first seating (2), exerting via a contact surface (4a) of the hook (4) a blocking action on the first attachment pin (101) housed internally of the first seating (2) which maintains the second attachment pin (102) blocked against a bottom surface (3a) of the second seating (3) situated opposite to the contact surface (4a) of the locking hook (4). The organ further comprises a safety block (5) predisposed to prevent a disengagement of the second attachment pin (102) from the second seating (3) in a case in which the blocking action exerted by the blocking pin (4) ceases to be active.
