A releasable clamp for the interior of an elongated tube, for use in telescopic tube arrangements and the like. The clamp comprises an outwardly expandable split ring having open ends and sides of cylindrical configuration, the sides of the split ring expanding outwardly to frictionally engage the interior surfaces of the tube when in expanded position, the split ring slidably movable longitudinally within the tube when the sides of the split ring are in unexpanded position. Wedges are provided, co-operating with the open ends of the split ring to bear against the ends of the split ring to force the sides of the split ring outwardly to expand it, tube engaging position. This releasable clamp may be used, for example, in an adjustable length handle for an appliance such as a floor polisher.
