Abstract
A method of forming a formlocking connection of two telescopic tubes and including providing in one of the two tubes at two diametrically opposite locations, elongate cut-outs, with the cut-outs having their respective end sides limited by at least one web, providing in another one of the two tubes, at two diametrically opposite locations, longitudinally extending strips extending from an end surface of the another one of the two tubes, inserting into the elongate cut-outs of the one of the two tubes, a forming tool, and thereafter, telescopically connecting the two tubes and pushing the two tubes toward each other so that the strips are pressed against the forming tool which causes the strips to roll over the webs, and a formlocking connection obtained by this method.
