Abstract:
A locking device for attachment of an artificial limb to an amputee's leg, comprising a coupling member arranged in a distal end of a sleeve that is adapted to receive the stump of the leg, and an adjustment head arranged on the artificial limb and connectable to the coupling member in laterally displaced positions relative thereto, wherein a locking ring is carried externally about the adjustment head, said locking ring being axially displaceable on the adjustment head and effective for adjustment of a distal length of the artificial limb, and effective for fixation of said adjusted distal length by frictionally arresting the locking ring on the adjustment head with an upper end of the locking ring in abutting contact with a lower surface of the coupling member, whereby the ring simultaneously effects a fixation of a translatory position of the artificial limb relative to the coupling member through the abutting contact with said lower surface of the coupling member.
