Beschreibung
Zusammenfassung:	The invention is a new telescopic rod provided with a truncated cone-shaped threaded opening element (Esf), applied to the inner tube (Ti), having a broad head (A), with protrusions and/or a ring (A), suitable for adhering to the end (Eg) of the outer tube (Te), in such away as to adhere - when the rod is completely lengthened - to the bush (Eg) of the outer tube. An expander (X) for the mutual constraint of the two tubes is applied to the opening element (Esf). The insertion of the inner tube into the outer tube is carried out by proceeding inversely with respect to the known technique, while the threaded head suitable for holding a broom or other tool is applied after the insertion.
