ABSTRACT:
A flat plastic retainer having a loop at one end rotatably receiving a threaded fastener and a tongue and outboard fingers unidirectionally extending from the loop to engage an essentially upright leg of a terminal of a circuit breaker, has lateral projections on the tongue which are compressed when the tongue is inserted through an opening in the leg of the terminal and expand when the projections pass beyond the opposite side of the terminal to resist pull-out of the retainer from the terminal. The outboard fingers are deflected along the terminal to bias the fastener into engagement with an associated leg of the terminal having an opening through which one portion of a threaded fastener pair projects to engage the other portion.
