Ski boot with a collar having a closure slide

A ski boot with a shell for a skier's foot comprising a lower shell having a front and a heel (1) intended to surround the foot and a boot leg (5) having a rear and an upper edge being in the form of a collar which is articulated on the lower shell and fitted, at the front, with at least one closure and tightening device (6, 7), wherein the boot leg has, at the rear, at least one slot (9) having edges and extending, from the upper edge of the boot leg, over most of the height of the boot leg, toward the heel, the edges of the slot having an overthickness (12, 13), the overthickness (13) of one of the edges having a male profile (15) and the overthickness (12) of the other edge having a matching female profile (14), so as to ensure mutual fastening of its edges by forcible engagement of the male profile into the female profile, and wherein the boot leg includes a closure slide (20) slidingly mounted astride the said edges, the displacement of the slide along said slot closes and opens the slot in the manner of a zipper, a safety slide (24) being arranged below the closure slide, means being provided for limiting the travel of the safety slide (24) at a point situated approximately half way up the slot (9), the two slides (20, 24) being connected by a flexible linkage member simultaneously constituting means for driving the safety slide (24) by the closure slide (20) and the means for limiting the travel of the safety slide.
