    摘要: The present invention relates to a closing device (10) for sports footwear, which comprises a rack (20) and a lever (40) suitable for engaging with the rack (20) in at least one position. The lever (40) consists of a lever arm (50) and a forked lug (60) which are connected together by means of a tie-piece (70).
    The rack (20), the lever arm (50) and the forked lug (60) are made of an aluminium alloy and have a surface hardness factor of at least 90 HB. A suitable material is a 7000 series aluminium alloy.
    The invention also relates to a method for manufacturing the closing device (10).
    The method involves extruding a 7000 series aluminium alloy billet, stamping the components of the fastener in a blanking press and boring the obtained component.
