Abstract
The invention relates to a tightening device including a strap portion provided with a serrated portion and with a tightening element, such as band or flap, on which is mounted a locking member including a base fixed on the tightening element; a ratchet connected to the base by a journal and having at least one complementary retaining serrated portion adapted to cooperate with the serrated portion of the strap portion; an elastic return device which maintains the serrated portions in contact with one another in the locking position; and a lever that can be actuated against the force exerted by the elastic return device for disengaging the serrated portions, wherein the strap portion engages through the locking member into a space provided between the journal and a complementary retaining serrated portion of the ratchet. The complementary retaining serrated portion of the ratchet is located with respect to the journal on the side where the strap portion engages into the locking member, such that in the locking position, the tightening torque that is exerted by the ratchet on the serrated portion increases proportionally to the tractional force exerted on the strap in the direction of disengagement out of the locking member. Such a device provides a tightening reliability as well as an ease of quick release with one hand.
