ABSTRACT:
This invention relates to a device for locking an adjusting finger in any one of the notches of a rack, wherein the first mobile element provided with the rack defines windows for the passage of retractable stops capable of being placed opposite the notches to stop the finger of the second mobile element, these stops being located at the free ends of flexible arms inclined in herringbone fashion and integral at their other ends with a sliding element provoking, when it is actuated, bending of said arms which abut on an edge of the windows and thus retraction of the stops.
