A telescopic tube ( 1 ) for an electric household appliance is described, said tube comprising a first outer tube ( 2 ) and a second inner tube ( 3 ) slidable inside said first outer tube ( 2 ), and electricity conduction means ( 10,18,20 ) for conducting electricity from first tube ( 2 ) to second tube ( 3 ). The conduction means comprise: a) an elongate guide body ( 7 ) made of a non electrically conductive material; b) a locking member ( 5 ) for connecting the first end of said elongated guide body ( 7 ) to said second inner tube ( 3 ); c) an outer channel ( 6 ) connected to an outer surface of said first outer tube ( 2 ), said outer channel ( 6 ) being provided for slidingly receiving said elongated guide body ( 7 ); d) a pair of tubular-shaped electric conductors ( 18 ) contained in said elongated guide body ( 7 ); and e) a corresponding pair of substantially rigid rod-shaped electric conductors ( 10 ) which are able to slide, at least partially, within said tubular-shaped electric conductors ( 18 ) so that each rod-shaped electric conductor ( 10 ) is in contact with an inner surface of a corresponding tubular-shaped electric conductor ( 18 ).
