A connector for towing cable or conduit in which one head includes a socket for the mating reception and breakaway of an aligned matching projection presented by the other head with the opposed aligned surfaces of socket and matching projection in sliding fit, a spring-loaded ball assembly presented by one head such that only a minor portion of the spring-loaded ball protrudes beyond its opposed aligned surface to register within a matching groove formation in the opposed aligned surface of the other head, and a set screw regulating the spring-loading of the ball so that displacement of the ball from the groove formation and breakaway occurs only when the tensile load applied to the mating heads exceeds the load imposed upon the ball; and with one head including a swivel shaft providing a connection to the other head and supported for rotation therewith upon a combination of dual thrust bearings at both ends including one or more of a three (3) piece needle bearing, a flanged Permaglide TM bearing or a radial thrust ball bearing and variations thereof. |
