In a device for closing a U-shaped clip about the gathered end of a wrapper and comprising a housing carrying a clip-closing die and, a punch pivotally mounted on the die to move from inoperative to clip-closing position in cooperation with the die, the improvement which comprises (a) a wedge shaped opening provided in one end face of the housing, the opening widening adjacent the apex to form a space for receiving the gathered end; (b) two gathering arms pivotally mounted on the housing on opposite sides of the wedge-shaped opening so that, upon pivoting, a gathered end within the opening is caused to enter the receiving space; and (c) a gathering nose on the punch; the punch being pivoted, only after the gathering arms have been closed, so that the nose engages and further compacts the gathered end against the die whereupon the punch applies the clip about the gathered end, the clip being closed by the die.
