Abstract: A connector assembly suitable for use with a leveraging system is disclosed. The assembly includes two connector components, each having an attachment component receiving portion and a pin-coupling portion. The pin-coupling portions cooperate, in an assembled connector assembly, to define a closed pin-receiving orifice passing through the connector assembly. The assembly can be quickly coupled to and from a fixed pin structure, thereby facilitating changing of an attachment component such as a knob hook. Additional features include a releasable securing device that secures the connector components into a connector assembly. Also, inclusion of a rounded transitional surface on each connector component permits use, and quick attachment, of the assembly in environments wherein space is otherwise unduly restricted around the pin to be coupled. A method for using the connector assembly is also disclosed.
