A barb connector ( 2 ) for use in a medical drainage device for draining fluid from a pleural cavity of a patient comprises a gripping portion ( 10 ), two cylindrical tubular members ( 11 ) extending outwardly from the gripping portion ( 10 ), and a plurality of annular protrusions ( 13 ) spaced-apart along the external surface of each of the tubular members ( 11 ). Each tubular member ( 11 ) comprises a plurality of recesses spaced-apart along the external surface of the tubular member ( 11 ), and the protrusions ( 13 ) are mounted in the recesses. Each protrusion ( 13 ) is of a compressible material. Upon insertion of a tubular member ( 11 ) into a lumen defined through a drain tube of the medical drainage device, the protrusions ( 13 ) engage the internal surface of the drain tube and deform to sealingly engage the internal surface. |
