Patent ID: 8851526

Claim:
An assembly comprising: a male fitting that defines a first angled interior passage; a female fitting that has a second interior passage defining a center axis; wherein the male fitting is configured to connect to the female fitting by insertion into the second interior passage to a predetermined position along the center axis so that the first angled interior passage is continuous with the second interior passage; a unitary cap having a terminal portion and a body portion extending from the terminal portion to define an inner cavity; wherein the body portion defines a first opening opposite the terminal portion and a second opening extending from the first opening toward the terminal portion; wherein the terminal portion has an inner surface facing the inner cavity and the body portion has a channel substantially surrounding an inner surface of the body portion; and wherein the inner surface of the terminal portion and the channel of the body portion are spaced relative to one another such that the unitary cap will connect to the male fitting and the female fitting with the inner surface of the terminal portion contacting an outer surface of the male fitting and the channel contacting a flange of the female fitting only if the male fitting is inserted into the female fitting to the predetermined position, the unitary component thus ensuring proper connection of the male fitting and the female fitting; wherein the male fitting has a first annular exterior channel; wherein the female fitting has a second annular exterior channel and apertures that extend through the female fitting at the second annular exterior channel; and a retaining clip configured to fit in the second annular exterior channel and extend through the apertures into the first annular exterior channel to limit relative movement of the male fitting and the female fitting along the center axis.
