A fastening device for connecting two identified openings (40,40a) in a shoe, the fastening device comprising: an elongated main body member defining a longitudinal axis, the main body member having a first end portion and a second end portion opposite of the first end portion at opposite ends of the longitudinal axis, first and second tip end members (37,37a), located at the first end portion and second end portion of the main body member, respectively, the first and second tip end members (37,37a) each being adapted to fit through one of the identified openings (40,40a) in the shoe; and a first elastic interference portion connecting the main body member and the first tip end member, and a second elastic interference portion connecting the main body member and the second tip end member, wherein the first and second elastic interference portions (33,33a) are each normally located in a rest state wherein the first and second elastic interference portions (33,33a) define an outer dimension that prevents their passage through one of the identified openings (40,40a) in the shoe, and the first and second elastic interference portions (33,33a) are elastically deformable into a state that permits their passage through one of the identified openings (40,40a) in the shoe, and wherein the first and second tip end members (37,37a) are coplanar with the first and second end portions, respectively, of the main body member, characterized in that each of the first and second elastic interference portions (37,37a) define an opening (34,34a) therethrough, that the first and second elastic interference portions (37,37a) are elastically deformable into a stretched state that permits their passage through one of the identified openings (40,40a) in the shoe and that each of the first and second tip end members (37,37a) has a substantially uniform width that is smaller in width than the elastic interference portions (33,33a). an elongated main body member defining a longitudinal axis, the main body member having a first end portion and a second end portion opposite of the first end portion at opposite ends of the longitudinal axis, first and second tip end members (37,37a), located at the first end portion and second end portion of the main body member, respectively, the first and second tip end members (37,37a) each being adapted to fit through one of the identified openings (40,40a) in the shoe; and a first elastic interference portion connecting the main body member and the first tip end member, and a second elastic interference portion connecting the main body member and the second tip end member, wherein the first and second elastic interference portions (33,33a) are each normally located in a rest state wherein the first and second elastic interference portions (33,33a) define an outer dimension that prevents their passage through one of the identified openings (40,40a) in the shoe, and the first and second elastic interference portions (33,33a) are elastically deformable into a state that permits their passage through one of the identified openings (40,40a) in the shoe, and wherein the first and second tip end members (37,37a) are coplanar with the first and second end portions, respectively, of the main body member, characterized in that each of the first and second elastic interference portions (37,37a) define an opening (34,34a) therethrough, that the first and second elastic interference portions (37,37a) are elastically deformable into a stretched state that permits their passage through one of the identified openings (40,40a) in the shoe and that each of the first and second tip end members (37,37a) has a substantially uniform width that is smaller in width than the elastic interference portions (33,33a).
