Lever for sports shoes, constituted by a free lever arm, one end whereof engages an abutment associated with a first flap to be fastened. A toothed strap is freely pivoted to the lever arm and selectively interacts, in a ratchet-like manner, with a first tooth of a pawl rigidly coupled to a second flap to be joined. The strap has a larger last tooth adapted to interfere with the first tooth of the pawl. The pawl has a second safety tooth for locking the larger last tooth of the strap once it has disengaged from the first tooth, so as to prevent its extraction. |
