A length-adjustable telescopic tube () has a longitudinal axis (L), an inner tube () and an outer tube (). In one of the tubes () a component () is arranged, which features first attachment structures (). The tube () has second attachment structures. Furthermore, at least one plug-in element ( and ) with third attachment structures ( and ) is provided, which cooperate with the first () and second attachment structures () to form a form-locking connection with the component () in at least one direction along the longitudinal axis (L) or perpendicular to the longitudinal axis. 11.
