The present invention provides a telescopic tube assembly. The assembly comprises a first tube and a second tube, wherein the external geometry of the second tube is adapted such that the second tube fits within the first tube, the first tube and the second tube being axially slidable relative to each other; a fastening member slidably engagable to the second tube and operable in use to fix the position of the first tube and the second tube relative to each other; and a lock slidably engagable to the first tube and connectable to the fastening member. The lock is adapted in use to secure the fastening member to the first tube so as to prevent the first tube and second tube becoming separated. |
