The breathing tube assembly is shown with a symbolic break in its length. The appearance of any portion of the article between the break lines forms no part of the claimed design.

The drawing is lined for color. The color and shading of the bead is a blue color value in the L*a*b* color space of L =42 to 48; a =10 to 18; b =−69 to −53 according to color measurement standard ISO 11664-4:2008(E)/CIE S 014-4/E:2007.

The references to “left,” “right,” “front,” “rear,” “top,” and “bottom” in the figure descriptions are not meant to require certain in-use orientation; the breathing tube according to the claim design may be used in any orientation.

The broken lines in the drawings depict portions of the breathing tube that form no part of the claimed design.
