Abstract
A locking device for a pair of telescopic tubes which assumes a locked position when the tubes are at rest. The locking device comprises a housing mounted around the telescopic tubes. Located interiorly of the housing is an end fitting and a collet with the collet being tightly pressed into engagement with the inner tube when the housing is in a retracted position. Longitudinal movement of the housing to an extended position will free the collet from the end fitting thereby permitting telescopic sliding movement of the tubes.
