Abstract: A guidance channel radiating from each side of clip holding chamber centered on a flat plate. A prying tool slideably and rotatably held within each guidance channel by a spring strip. A split ring held snugly within the holding chamber. The tool tips are forced between the split ring coils, which are separated further by simultaneous rotation of the prying tool handles 90-degrees in opposite clock directions.
