DEFINITION

Classification: 411/202

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

(under subclass 191) Device wherein either (a) an inherent property of resiliency on the part of at least one of the distinct members or (b) the presence of a distinct element having such a capability, is relied upon for either (1) moving the distinct member into or from its rotation restricting position or (2) keeping the distinct member from becoming separated from its operative association with one or the other of the threaded elements.
