A locking device for a lace or cord, comprising:
- a base configured to be fixed to a product including the lace or cord to be locked and including at least one passage seat for passage of the lace or cord to be locked;
- a lever including at least one element for pinching the lace or cord in the at least one passage seat, and at least one guiding seat for the lace or cord;
- the lever being connected to the base, proximate to the at least one passage seat, by pivoting means that define for it a rotation axis, around which the lever is configured to rotate with respect to the base to pass reversibly:
- from an open configuration, in which the at least one passage seat is free from the at least one pinching element, the lace or cord passing through and configured to slide freely within the at least one passage seat,
- to a closure configuration, in which the lever is folded down onto the base, the at least one pinching element engaging the at least one passage seat so as to pinch thereat the lace or cord to prevent sliding in the at least one passage seat, an end portion of the lace or cord passing through the at least one guiding seat to be directed in a preselected reverse direction, which is defined by the at least one guiding seat,
- and vice versa,
- wherein the base includes two side walls, which delimit laterally the at least one passage seat, which is substantially shaped like a channel to receive and accommodate an arm of the lever when the lever is in the closure configuration,
- wherein the pivoting means comprises a pivot that passes through a first end of the lever transversely to the side walls that support it, so as to define the rotation axis substantially transverse to the passage direction of the lace or cord in the at least one passage seat, which is defined by an extension of the passage seat, and
- wherein the at least one guiding seat comprises at least one first guiding seat that passes through the first end in a direction substantially longitudinal to the lever.
