A split resilient retainng ring (100) is provided that features corresponding slots (14,16) that extend circumferentially away from each other in substantial parallel relationship to the inner periphery (4) and outer periphery (6) of the ring's body portion (2) and that end in apertures (18 and (20) respectively that have a breadth greater than the width of slots (14,16). The slots (14,16) and apertures (18,20) enable fingers (22,22') of a manipulating tool (24) to be inserted thereinto and move circumferentially away from each other along slots (14) and (16) and into apertures (18) and (20) for radially expanding and contracting ring (100) for seating in a groove. A cutting tool (800) is also provided for cutting the profiled trapezoidal configuration providing slot (14) and aperture (18) facing slot (16) and aperture (20) across the split between opposed ends (10) and (12) of ring (100).
