DEFINITION

Classification: 411/210

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

(under subclass 209) Device wherein either (a) an inherent property of resiliency on the part of the pin, wedge, clip, dog, etc., or (b) the presence of a distinct element having such a capability, is relied upon for either (1) moving the pin, etc., into or from its locking position or (2) keeping the pin, etc., from becoming separated from its operative association with one or the other of the threaded elements.
