Abstract
A spring-biased detent to provide selective securement of a door knob assembly to a spindle of a lock mechanism. The detent is inserted transversely in the spindle and biased by a spring clip. The detent may be depressed within the spindle allowing the door knob assembly to slide onto the spindle and subsequently is biased into an aperture of the knob to lockingly attach the knob assembly to the spindle. The detent includes a central aperture for receiving a tailpiece of the lock mechanism. The aperture is configured to allow depression of the detent only when the tailpiece is oriented in an unlocked position preventing removal of the door knob assembly when the latch is locked.
