The invention relates to a safety lead in the form of a sewn strap for the safety of a person participating in speleology (caving), the descent of canyons and work carried out at a height. The central attachment loop 12 is connected to the two branches 14, 16 of the lead 10 by two links 18, 20 with stitching (seams) 44, 46. In the event of a shock on one of the branches, for example 14, the stitching 44 of the first link 18 resists the shearing effect, whilst the stitching 46 of the second link 20 yields by moving away in order to create a shock-absorbing effect. <IMAGE> |
