Abstract: A plug having a longitudinal axis includes a plug body having a generally flat sealing surface on an axial end thereof, and a protuberance extending from the axial end generally concentric with the longitudinal axis. The protuberance has a first section contiguous with the plug body, and a second section having a hub portion contiguous with the first section and a plurality of generally evenly spaced arms extending outward from the hub portion. An underside surface of each arm faces the sealing surface of the plug body and has a generally flat portion and a ramped nub thereon projecting toward the sealing surface. The plug may be inserted into a compatible socket having tabs and rotated about the longitudinal axis for sealable engagement with the socket.
