Abstract: An adjustable-length pole (10) for sticks, having an outer tube (12) and an inner tube (11) that can be inserted telescope-like into the outer tube (12) for adjusting the length of the tube, and having a spreading device (15) that is supported at the insertion end of the inner tube (11), the spreading device being able to clamp the inner tube (11) axially in the outer tube (12) and having a spreading element (16) that can be radially pressed apart and that is furnished with an inner cone (27), an interior element (17) that is provided with a reverse-oriented outer cone (22) and that is accommodated in the spreading element (16) so as to be axially movable, and an adjusting screw (18) that is axially oriented and is supported in a rotationally fixed manner on the inner tube (11), the adjusting screw having an operational connection to an internally threaded bore (21) in the interior element (17).
