    摘要： Kit members used to replace and convert conventional push-pull automobile door latches with operating vertical reciprocatable spindle means against internal accidental release or external unauthorized release. The conventional latch knob is first removed, thereby exposing the threaded end of the spindle at the usual opening formed in the door sill for connection with the kit members. The kit comprises a guide sleeve, a latch knob with a hollow shank with bifurcated end portions to thread on the exposed end of the spindle, shroud means around the latch knob with an opening to permit under knob engagement by suitable means, and a highly flexible grommet coupled with the shroud around the latch knob conformable to the exterior top surface of the door sill. The guide sleeve being snapped into place in response to downward pressure exerted on a split ring tool member against the bias of a tension spring and discarded prior to connection of the latch knob on the spindle with the coupled shroud and grommet. The guide sleeve having an adapter sleeve with elongated longitudinal slots carried thereby when an enlarged spindle hole is encountered in some makes of automobiles.
