An adapter is provided consisting of a tubular center section and a pair of circular flange sections at each end of the tubular center section. One of the flanges is removable so that coils of tie material such as string, cord, wire, or plastic or paper covered wire and the like can be placed on the adapter and the flange replaced. The tube is segmented circumferentially and can be expanded to tightly engage the inside surface of the coil. One of the flanges floats axially on the adapter and is resiliently biased in the direction of the other flange to tightly engage the side surfaces of the wound up coil.
