The element has a rod (5) extending along a longitudinal axis and provided with a cord (6) including a cover made of an elastic material. A fixation sheath (8) surrounds the rod and includes rigid zones (9) spaced with respect to each other at a distance lower than a nominal length of a contact zone (11), where the contact zone is defined by locking units (4) that lock the element on anchoring units. The rigid zones include slots for fixing the sheath on the cover, where the rigid zones include distinct rings (10). |
