Abstract: In a marine anchor for coupling a tether to an anchoring chamber the tether terminates at a connector having a flange that abuts a flange of an anchoring chamber. A collet connector is expandible to trap flanges, in an external groove thereof, thereby establishing a primary load path. The mouth of the anchoring chamber is further provided with an out-turned flange engaged by locking fingers and operable by actuator means to establish a secondary load path from the anchoring chamber to the tether while the anchor is being established or released. The coupling can be separated without damage under high loads or when the tether is at an angle to the chamber.
