Abstract: A cylindrical reel-hub for a tape, in particular a magnetic-tape or ink ribbon, is divided in into two semicylindrical reel-hub portions along a dividing zone. The reel-hub portions are integrally interconnected by an elastically deformable bridge which bounds the dividing zone at one end and which constitutes a hinge between the two reel-hub portions. The reel-hub portions are held together by a connecting means at the open end of the dividing zone to clamp a tape introduced into the clamping zone between them. The two ends of the dividing zone are substantially diametrically opposite one another and the dividing zone extends in a substantially radial direction at its open end.
