MECHANISM COMPRISING TUBULAR an outer shell (7) and an inner element (10 to 12) forming a hollow interior WITH A VOID IN CROSS SECTION; TUBULAR said cover (7) and said INTERNAL (10 to 12) has two sections (7A, 7B; 10, 12) having different diameters; TOP SECTIONS (7A, 12) smaller diameter housed inside CYLINDER NEEDLE (1), while sections LOWER (7B, 10) of smaller diameter are located OUT AND ADJACENT TO THE NEEDLE CYLINDER; Between the two sections (12, 12A, 10, 10A) of said inner member is formed an annular discontinuity (D), SO AFTER A FIRST PHASE INVOLVING TRAINING WITH TENSION NEUMATICO can take place through said DISCONTINUITY A SECOND PHASE INVOLVING BENDING INTERNAL and reversibility.
