Abstract: A device for attaching a retaining string to headwear is comprised of first, second and third relatively flat tab members, which are substantially co-planar. The first and second tab members are oriented along a common axis, while the third tab member is oriented along an axis which is substantially orthogonal with respect to the common axis of the first and second tab members to define a substantially T-shaped device. The transition between the third tab member and each of the first and second tab members defines a corresponding curved edge. To attach the retaining string, the third tab member is inserted between the crown portion of the headwear and the flexible band on the inside of the crown portion and down through the stitches which attach the band to the crown portion. The first and second tab members engage the stitches to retain the device in position behind the band. The distal portion of the third tab member extends below the band and is adapted to be attached to one end of the retaining string.
