Silicone lace with a strong visual identity and improved tear strength, and lacing system formed by a plate for locking the lace in place on the shoe

The invention is intended to provide silicone elastomer laces that are improved in terms of branding and/or ornamentation and/or tear strength and/or additional novel functions other than the mechanical properties and external appearance thereof, as well as a novel lacing solution. For this purpose, the invention relates first to a lace (1) for a shoe (2) equipped with a lace passage (3), the two edges (4, 5) of said passage having through-holes (7). The lace (1) essentially comprises at least one silicone elastomer that is at least partially cross-linked and includes one or more silicone polymers and fillers and, optionally, at least one of the following compounds: catalyst(s), cross-linking agent(s), pigment(s), parting agent(s), plasticiser(s), adhesion promoter(s). The lace is characterised in that it comprises, in the middle portion thereof, an identification zone (9) which is integral with the lace (1) and which, once the lace (1) has been passed through the through-holes (7, 7i) of the shoe (2), is intended to appear on the instep of the shoe (2), between the two lower through-holes (7i) located on either side, and at the base of, the lace passage (3) on the shoe (2). The invention also relates to a lace intended to be locked in place on the shoe (2) using a so-called "BlocKnot" plate (30) that is provided with multiple passages (20) for holding the lace (1) in place when the free ends of the strands (8
