The device has a rigid tubular support (10) of elongated form presenting a longitudinal slit (11) on its entire length, where the slit permits insertion of a cord and a sheath (5) in the support. A ring permits the maintenance of the sheath of the cord at the end of the support. Three brackets are respectively fixed on a front crosspiece and on both sides of a lock (3), and the ring is pushed in the support. |
