Articulated connecting element for piping elements

A flexible conduit includes a corrugated tubular metal bellows having a minimum inner diameter; cylindrical end fittings secured to the bellows; a metal hose disposed coaxially within the bellows and having a maximum outer diameter which is less than the minimum inner diameter of the bellows; and a free annular cylindrical space situated between the bellows and the metal hose. The cylindrical space has an outer diameter equaling the minimum inner diameter of the bellows and an inner diameter equaling the maximum outer diameter of the metal hose. The conduit further has a hollow cylindrical knit wire element positioned in the cylindrical space. The knit wire element radially fully occupies the cylindrical space without projecting radially therefrom.
