Abstract

Abstract A cable connector suited for underwater salvage operations by diver-swimmers having an engagable male and a female part. The male member is attached to a hoisting line and flotation gear and the female part is attached to the load. A hauling line attached to the male member, leads away from the head, threads into the central barrel and over a sheave in the female part. Pulling on the hauling line brings the two parts into locking engagement. Spring-loaded cammable latches on the female part engage the head of the male member for a swivel connection.
