DEFINITION

Classification: 411/206

Utilizing a resilient characteristic of the key, or of a discrete element:

(under subclass 205) Device wherein either (a) an inherent property of resiliency on the part of the jointed pin, hinged plate, bendable rod, etc., or (b) the presence of a distinct element having such a capability, is relied upon for either (1) moving the jointed pin, etc., into or from its locking position or (2) keeping the jointed pin, etc., from becoming separated from its operative association with one or the

other of the threaded elements.
