ABSTRACT:
Simplified hook closure for a sport boot including an elastic means for returning into a position pressed against the shell of the boot. The hook closure has at least one element, such as a lever made out of flexible metal wire in the form of an open buckle whose lateral arms are of unequal lengths of a value "X", the curved ends of the said arms being affixed in corresponding holes formed on another element, such as a base, on which it is mounted. By virtue of the offset "X" of the curved ends of the element, any pivoting of the latter generates a certain elastic deformation of its arms, which automatically return to their initial position as soon as the lever is released thus assuring the elastic return function.
