ABSTRACT:
An elastic ring for maintaining a pin in a hole formed in a socket and work drive shaft of a rotary tool. The ring has integral fingers which project into the ends of the hole so that the pin cannot dislodge the ring by centrifugal force when the tool is operating at high speed. Several variations of the ring include weighted areas at portions of the ring midway between the fingers, which areas counterbalance centrifugal force on the ring to supplement holding force of the fingers upon the pin.
