The slider (81 to 873, 9, 91, 92) is unitary with one element, the guide track (72, 73) with a second element. The slider (81) comprises two flexible arms (82, 83) which contact and cooperate with the sides (72, 73) of the guide track. A control lever (9), jointed onto the slider (81) around an axis (91), has a projection (92) which, for the purpose of fixing the slider (81 to 83) in position, fits between the arms (82, 83) so as to hold them against the edges of the guide track (72, 73) when the lever (9) is set in the locked position. Complementary forms (10), which interlock in the locked position, are advantageously provided on the arms (82, 83) and the edges of the guide track (72, 73) in order to ensure positive positioning. The invention is applied in particular to the adjustment of the geometric and mechanical operating characteristics of ski boots, especially to those having a shaft jointed onto a shell base. |
