Abstract: A protective device for golf clubs includes a pair of relatively non-extensible straps that are attached at one end to a cap and at the other end to the open end of a golf club head cover. When the head cover is placed on the golf club, the cap can be placed on the grip end of the club so as to apply a slight tension to the head cover by way of the straps. Accordingly, the head cover will be maintained in place on the golf club. The device can be provided to consumers for attachment to existing head covers, or it can be provided to consumers as an assembled head cover-straps-cap unit. In alternative embodiments, the straps can be connected releasably to the head cover, and the length of the straps can be adjusted to accommodate clubs or head covers of different lengths.
