Abstract
A pair of tubular coupling members (2, 3) are joined in a telescopic relationship to form a continuous passageway (25) of substantially uniform diameter. A plurality of resilient clamping fingers (27) are biased in a radially outward direction and axially extend from one coupling member (3) to surround an annular projection (10) provided by another coupling member (2). A slidable annular locking sleeve (4) removably engages camming surfaces (25) to urge the clamping fingers (22) into firm locking engagement to surround the annular projection (10) and securely maintain the coupling members (2, 3) together. The connector maintains a fluid tight seal without directly subjecting a gasket (12) to the solutions to maintain a sterile connection.
