A riser connector connects the upper portion of a riser ( 12 ) having a latching enlargement ( 32 ) to a receptacle ( 14 ) on a vessel ( 16 ), so the riser upper end ( 22 ) can connect to a fluid coupling ( 42 ) leading to a conduit ( 40 ) on the vessel. A double-click mechanism ( 88 ), with parts on the enlargement and on the receptacle, turns a load ring on the enlargement to latch the enlargement in place when it is lifted to an upper position and lowered to a latched position, and releases it by again lifting and lowering. A cable coupling ( 24 ) is temporarily mounted on the top of the riser to enable the riser to be lifted by a cable ( 26 ), the cable coupling being later removed to connect the riser upper end to the fluid coupling on the vessel.
