ABSTRACT:
A split ring opening hand tool is shown in the form of a modified pair of long nosed pliers. One jaw carries a support for a split ring while the other jaws carries a probe that passes between the convolutions of the split ring as the jaws are moved to their closed positions. The probe has a laterally facing inclined surface that converges on the tip end of the probe and the support has a groove which provides a laterally facing inclined surface that is encountered by the probe tip end after it passes through the convolutions. This causes relative lateral movement of the jaws as the convolutions are being spread apart by the relative movement of the probe support.
