A supple bag can be held open or closed by two handles (1,2) which are fit round the top opening of the sack. The radius of the outer handle is greater than that of the inner handle. The handles are assembled by buckles (3) at the ends of the outer handle (1) closing on triangular buckles (4) at the ends of the inner handle. During their assembly a compression is introduced into the outer handle when its two buckles are brought together to be closed on the triangular buckles. The bases of the triangular buckles are larger than the other buckles such that they retain them and maintain the compression in the outer handle.
