Abstract
Abstract A device for closing filled sacks and bags, such as refuse sacks, has a flat clamping plate with an opening to accommodate the gathered or twisted neck of the sack and accessible from the outside via resiliently spreadable gap in the plate. A carrying grip is formed by the web of a stirrup and two legs of the latter converge towards the sides of the grip in the direction of the plate.
