ABSTRACT:
The device comprises a toothed strap with saw teeth (4), which is fixed, at one of its ends, to the boot (1) and carries a sliding U-piece (7) on which a ratchet (8) cooperating with the toothed strap is pivotably mounted. Above these teeth (10), the ratchet has a groove (11) inside which the bar (11) of a buckle (14) integral with another part of the boot is engaged. The U-piece is provided with two hook-shaped recesses located opposite the groove (11). The hinging pin (15) of the buckle, which at the same time acts as a tensioning lever, engages inside a groove (13). The ratchet pin is subject to a small degree of strain and accidental opening of the buckle due to pressure on the end of the latter is prevented.
