DEFINITION

Classification: 285/205

(under subclass 201) Subject matter comprising a short tube (nipple) flanged on one end and having means, e.g., a nut, wedging ring etc., coacting therewith to clamp the wall between them.

(1) Note. Sputs under subclasses 205+ generally comprise more than one piece and coaction, as by thread, between the pieces produces clamping.
