A ski pole which allows one to correctly adjust the overall length of the pole to skier's height. It embodies upper and lower pole sections whose adjacent coacting ends are telescopingly joined and are equipped with manually regulatable coupling means. This coupling means embodies an outer nut-like sleeve having an internal stop shoulder at its lower end and wholly encompassing a longitudinally split inner expansible and contractible sleeve which when clampingly contracted provides a friction held retainer. The lower tapered end of the outer sleeve is cooperatively oriented with a graduated pole length measuring scale provided on the peripheral surface of the lower section of the pole. |
