Abstract
An anti-buckling device capable of guiding a cylindrical element (3) that is pushed and moved over a given distance C in the direction of its axis XX', said device being made up of at least two elementary cylindrical tubes (2) that are nested and guided mutually in one another in order to form a tubular telescopic assembly (1) of axis XX' and of given length L, such that at least one of said elementary tubes (2i) comprises a transverse support (6i) having an orifice (7i) arranged inside the cylinder of the elementary tube capable of guiding said cylindrical element (3) fitted into this orifice (7i) and pushed through this telescopic assembly (1).
