Each "locking kit" includes two tubular aluminum bars, specially grooved at the bottom and top to ensure their good adhesion to the surface of the conveyor belt during repair operations. Two locking clamps are made of tubular profile and shaped so as to provide the insertion of the ribbon inside for proper attachment with the appropriate screw which, from above, guarantees their seal. Outside the fastening clamps, traction supports are formed of a shaped ring that incorporates the tubular and provided with a suitable hole for use by inserting a tie or link chain between two opposed clamps.
