Ortloff, J E

A quick-release connector is described for securing two offshore mooring sections comprising: a pin member attached to one end of one mooring section; a latch member having a hook at one end with an open region adapted to engage the pin member and to rotate concentrically on a fixed axis substantially corresponding to the pin member when in engagement. The latch member is attached to one end of the other mooring section; a plunger adapted for axial movement between a first position, where the plunger is displaced from the open region of the hook. This permits the rotational movement of the latch, and a second position, wherein the plunger advances within the open region of the hook, prohibiting the rotational movement; means for rotating the latch member about the pin member; and means for longitudinally displacing the plunger between the first and second positions.
