Abstract: Connecting device between a lower shell and a cuff of a ski boot, the ski boot comprising a lower shell, a cuff and a connecting device between the lower shell and the cuff, the connecting device comprising: a connecting ring configured to guide the cuff in rotation relative to the lower shell, a locking element that is movable between a first position and a second position, the locking element being able to prevent the connecting ring from rotating relative to the locking element when it is in its first position, a retaining element configured to retain the locking element in its first position.

Abstract: Gliding boot (1) including a lower shell (2) and a collar (4), the lower shell (2) being intended to receive a user's foot, the collar (4) being intended to envelop a lower leg of the user, the collar being articulated in rotation about the lower shell, the gliding boot further including an upwardly extending tongue (10) to the rear of the gliding boot and an elastic means (26), a first end of the tongue being fastened to the lower shell (2), and a second end of the tongue (10) being connected to the collar (4) via the elastic means (26).

Abstract: A locking and unlocking device includes an actuation element and a lock and a rear deflector. The actuation element is mobile between a first position and a second position, controlling the position of the lock and the position of the rear deflector such that in the first position, the lock occupies a locking position to block an upper cuff in rotation relative to a shell base, and the rear deflector occupies a low position to close a cut-out at the rear of a shell base; and in the second position, the lock occupies an unlocking position to release the rotation of an upper cuff relative to a shell base, and the rear deflector occupies a high position to open up at least partly a cut-out at the rear of a shell base, in order to increase the amplitude of flexure of a lower leg in a sports boot.
