A hollow body 14 contains a shaft 18 around which are mounted a rotation elastic return means 23 acting on two opposed flats 18A, a piston 20 activating this elastic return means 23 at will, a second piston 35 pushed by a spring 39 in order to clamp or free a disc 19 which is fixed to the shaft 18 with respect to an internal partition 31 in such a way that this articulation can have three separate states: free, locked, elastically returned to any locked position.
