ABSTRACT:
A biasing spring especially for a doorknob keeper or other knob to knob-sleeve connector and the combination thereof with a knob connector of any of various types, but in particular a plate mounted for radial movement in a plane normal to the axis of a knob sleeve and having a lug projecting radially into engagement with a surrounding knob portion. The spring has a central angular bight embracing a central tongue on the retainer plate at one side of the sleeve, and side legs straddling a central clearance space in the knob sleeve and extending into stressed camming engagement with converging inside faces of the opposite half of the sleeve. The spring legs may have end portions interlocked with the plate to secure the spring in place, or may be otherwise retained.
