Claim 1
Independent Claim
201 words
A connector for a multiple passage tube, the connector comprising a body portion having at least a first tube receiving end of generally cylindrical configuration, the first tube receiving end having defined therein a first passageway and a second passageway, each of the passageways being in full communication with space external to the first end, the body defining at least one wall separating the first and second passages, the wall between said first and second passages at a location adjacent the first end defining a first end slot extending inwardly into the wall from said first tube receiving end, the first end slot being generally parallel the first and second passageway and communicating with space external to the first tube receiving end both in axial and diametrical direction, a second end of generally cylindrical configuration, having a second end first passageway and a second end second passageway, said second end passageways being in full communication with first and second passageways of the first end, the second end defining a second end slot extending toward the first end slot, the second end slot disposed between the first end first and second passageways, the first and second slots being of generally like configuration.
