The device comprises a ratchet (3) and a base (4) that are to be respectively secured to the two footwear portions (A, B) to be closed on one another, a sprocket wheel (12) supported on the base (4) to be rotatable about an axis substantially perpendicular to the sliding direction of the ratchet (3), a lever (8) mounted on the base (4) so that it can be swung about the axis of the sprocket wheel (12), as well as first (13, 15) and second (26) unidirectional retaining means respectively between the lever (8) and the sprocket wheel (12), for the rotation of the sprocket wheel and the resultant sliding in one direction of the ratchet (3), and for holding the ratchet with respect to the base (4) in the opposite direction; the first unidirectional retaining means comprise a coupling having front teeth (13, 15), which coupling acts between one axial end of the sprocket wheel and the lever.

Le dispositif comprend un secteur denté (3) et une base (4) qui doivent être fixés respectivement aux deux parties d'articles chaussants (A, B) de façon à se refermer l'un sur l'autre, un pignon (12) appuyé sur la base (4) de façon à pouvoir tourner selon un axe essentiellement perpendiculaire au sens de coulissement du secteur denté (3), un levier (8) monté sur la base (4), de façon à pouvoir basculer par rapport à l'axe du secteur denté (12), de même qu'un premier (13, 15) et un second (26) moyens de retenue unidirectionnels, respectivement disposés entre le levier (8) et le secteur denté (12), de façon à faire tourner le pignon et à entraîner le coulissement dans un sens du secteur denté (3), et à retenir le secteur denté par rapport à la base (4) dans le sens opposé; le premier moyen de retenue unidirectionnel comprend un accouplement à dent avant (13, 15), lequel accouplement agit entre une extrémité axiale du pignon et le levier.
