Telescopic support tube for a metal detector (metal detecting device)

摘要

A telescopic tube for a metal detector is provided, which consists of at least one inner tube (6, 7) and an outer tube (5). The tubes can be clamped against one another in a desired length position by means of clamping devices (8, 9). Webs (16, 17) joined to guiding grooves (21) ensure that the tubes do not rotate relative to one another during the locking operation. <IMAGE>
