ABSTRACT:
A door knob on a knob sleeve or spindle which is adapted to be blocked from rotation is connected to such spindle by a break-away ring and is otherwise rotatable on the spindle. The break-away ring is mounted about the spindle between the end of the fixed hub of the lock chassis and an internal flange on the knob, and has a pair of radial lugs extending inward to key it to the spindle and a pair of axial lugs extending into the knob flange to key it to the knob. One pair, preferably the axial pair of lugs, is adapted to break away under excessive knob turning force to disconnect the rotative connection of the knob to the spindle.
