  • Patent number: 4322077
    Abstract: A wrist band is attached to the handle of a tennis racket for use in securing the tennis racket to the wrist of a player. The wrist band can be attached to the handle of an existing tennis racket without requiring removal of the grip. The wrist band includes a flexible strap having a pair of ends fixed together by a sleeve secured over the adjacent ends of the strap for forming a fixed loop of the wrist band. The sleeve has a generally rounded outer surface and a rim that projects outwardly from the rounded surface of the sleeve. A base plate loosely fitted around the outer surface of the sleeve protrudes outwardly away from the rim on the sleeve and is retained around the sleeve by engagement with the rim. The sleeve and the base plate can be inserted in a hole drilled in the end of the racket handle, with the base plate bearing against the end of the handle and bridging the hole to retain the strap in the end of the handle.
