A device (2) for locking a shutter or the like in different angular opening positions, comprising a cylindrical body (6) insertable on the upper part (3') of the lower hinge (3, 3') of the wing (4). A lever (8) rotatable around an axis that is substantially orthogonal to the rotation axis of the wing (4) allows locking the wing, making it abut against the fixed frame (5) of the shutter or the like. |
