Abstract
A locking device for a pair of telescoping tubular poles. An engagement member fits to one end of first pole and is slidingly engaged within second pole. A groove of the engagement member engages with a rib in the second pole so the first pole cannot rotate relative to the second pole. First pole also slidingly engages through a clamp which is mounted to the end of the second pole. A cover fits over the clamp. A cam located between the inside wall over engages with a clamping element of the clamp. A lever extends from cam through an opening in the cover. By manipulating the lever the cam can cause the clamping element to clampingly lock the first pole against sliding movement in the second pole.
