DEFINITION

Classification: 411/323

And including a plastically deformable portion:

(under subclass 321) Device wherein the dowel, pin, rod, 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 dowel, 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.
