ABSTRACT OF THE DISCLOSURE: Tubular wrapper closing combination made up of a bar of clips each adapted to close a tubular wrapper, bag or the like, and a closing device for each clip. Each such clip is a curved U-shaped length of metal wire of which the ends of the legs thereof are bent inwardly toward one another and each leg has an outwardly bulging portion. The closing device is formed with a clip guideway and is provided with a mechanism for forcing advancement of the bar toward the guideway to feed the clips into it. The closing device further includes a die in the guideway for closing the clips and a retractable punch for advancing one of the clips at a time into the guideway towards the die and thereby to close around the tubular wrapper. The punch has a pair of side portions with respective recesses for receiving the outwardly bulging portions of the legs of the clips so that, upon retraction of the punch, should the clip not be closed, it will he retracted with the punch so as not to permit the next clip of the bar to be fed into the guideway.
