Abstract : The patent relates to a device whereby a remote interconnection of a first undersea vehicle tethered to a second undersea vehicle is assured by mating assemblies carried on both vehicles. The tethering cable extends through a prod assembly carried on the tethered vehicle and functions mainly to deploy and retrieve the tethered vehicle. During the connection of the two vehicles the cable serves to draw the prod assembly into a latching assembly carried on the second undersea vehicle. Several pawls are cammed into an annular groove on the prod assembly and a pair of opposing helical springs mechanically interact to lock the pawls in place. The coaction of the springs' working on a collar on the prod assembly and a sleeve on the latching assembly makes accidental disengagement nearly impossible until hydraulic actuators assist the force produced by the sleeve spring to overcome the force exerted by the collar spring to release the pawls.
