Disclosed is a multiple telescopic tube comprising at least two parallel outer tubes ( 1 ), at least two inner tubes ( 2 ) which are disposed parallel to the outer tubes ( 1 ) and are movable relative to said outer tubes ( 1 ) in a longitudinal direction (Z), and a clamping device ( 3 ) which is provided with a clamping engagement element ( 5 ) that can be made to engage with the exterior surfaces of the inner tubes ( 2 ). The clamping device ( 3 ) prevents displacement of the inner tubes ( 2 ) relative to the outer tubes ( 1 ) in a longitudinal clamping direction while the inner tubes ( 2 ) remain movable in the opposite longitudinal direction when the multiple telescopic tube is subjected to a load in said longitudinal clamping direction. The inventive multiple telescopic tube can be used as a leg of a camera stand, for example. |
