Abstract
A tendon or riser connector has a separate lock-down device that overrides the connector's ability to unlock if the riser or tendon goes slack. The connector has a lock ring that engages a groove profile on a receptacle and is prevented from accidentally unlocking with a cam ring and set of blocks. The blocks are movably positioned between engaged and disengaged positions that correspond to the locked and unlocked positions of the lock ring.
