Abstract: A coupling device enabling rapid connection and disconnection of lifting wires or similar articles for attachment by an ROV to/from a submerged object comprising a main body portion (1), a hook potion (2), a closing member operated by a member (5) and a separate safety latch (4) arranged to lock the closing member when closed such that a load cannot escape the hook portion, the latch member and closing member being further arranged such that a gripping action (A, B) on two opposite sides of the body portion will automatically release said latch member and move the closing member into the open configuration while the device is held bodily under said gripping action, the closing member and latch member being spring biased so as to close and then lock the hook automatically when the grip is released.
