DEFINITION

Classification: 411/212

Including plastically deformable portion:

(under subclass 209) Device wherein the pin, wedge, clip, dog, etc., has at least one region which, when bent or otherwise reshaped, is adapted to remain in its changed configuration (i.e., the elastic limit of the material from which the pin, etc., is formed has been exceeded).

(1) Note. The reshaping may relate to the retaining of the member in its operative position, rather than to the member's function of restricting rotation.
