Abstract: A swivel connector is provided for use in either an intravenous liquid supply line or an oxygen supply line to allow the line to rotate to prevent kinking. A body portion is provided having a cylindrical cavity formed in one end thereof, and a hollow, cylindrical male member slides into the cylindrical cavity and has sufficient clearance to allow free rotation of the male member within the cylindrical cavity. A locking flange is carried by the male member which engages an annular groove formed in the body portion to prevent the male member from inadvertently disengaging from the body portion. A seal is also provided between the male member and the body.
