ABSTRACT:
The connector of the instant invention includes an elongate body having a side wall thereabout, a base at one end thereof and a nubbin-receiving chamber therein. The chamber has an upper, nubbin-insertion region which is sized freely to receive a nubbin therein, and a lower, nubbin-seating region. The chamber has a first opening in the side wall adjacent the upper region which is sized to allow passage of a nubbin therethrough. A second opening is provided in the side wall which is located below and connected to the first opening and extends into the base. The second opening is sized to allow passage only of a cable therethrough. A spring-biased nubbin retainer is located at the upper end of the nubbin-insertion region and includes a shaft which extends through and is axially moveable in the upper end of the nubbin-insertion region. A plate is mounted on the end of the shaft in the nubbin-insertion region. The shaft and plate are arranged such that the plate, when fully extended into the insertion region, is spaced apart from a nubbin seated in the seating region. An attachment structure is located at the other end of the body for attaching the connector to a hauling line. A formation is located adjacent the other end of the body and has an assymmetry characteristic which prevents adjacent connectors on a line from stack-nesting.
