Abstract: A two-part connector (1) is provided for use in connecting and disconnecting fluid carrying conduits. The connector comprises lower and upper parts (2, 3) each having four fluid carrying duct (15) therethrough, and a valve member (17) for each duct. Each duct in the lower part (2) is aligned with its respective duct in the upper part (3) when the two connector parts are connected together. The connector has clamps (24) for retaining the lower and upper parts (2, 3) together in sealing engagement. The clamps are mounted on the upper connector part (3) and are pivotable thereabout. Hydraulic pistons are used to move the clamps, the clamps being located in a first position pivoted away from the connector whilst the lower and upper parts (2, 3) are being aligned relative to each other.
