A device for positioning a deflection yoke about the gun portion of a cathode-ray tube. The yoke-retaining device is formed of a molded plastic material and has a collar or ring portion which is supported against the rear envelope of the tube by a series of integrally formed leg members. The collar portion has a series of integrally formed springlike tabs which project radially inwardly of the retainer to center the yoke within the ring. The tablike spring members hold the yoke firmly in directions transverse to the axis of the retainer, while permitting free movement of the yoke in the axial direction. A series of flanges are provided at the leg side of the collar portion to confine the yoke within the retaining device. Each of the flanges has a guide rib associated therewith extending in the axial direction at spaced points along the inner surface of the collar portion. These ribs prevent substantial pivoting of the yoke as it is being positioned within the yoke retainer.
