DEFINITION

Classification: 24/548

Resilient gripping member having tightly twisted portion:

(under subclass 546) Resilient* body having two portions thereof which are closely, securely, and successively wrapped about one another by each portion subtending an arc of 720 deg. or greater.

(1) Note. Both portions of the gripping member must cooperate in the wrapping or twisting to be proper herein. A portion which is just wrapped about a passive (e.g., straight) portion is considered to be coiled and not twisted. A coiled portion which is merely threaded through another coiled portion is not considered to be twisted since it is not securely wrapped thereabout.
