Door latch with privacy feature

A snap ring removal/installation tool for removing crescent shaped split snap ring from a snap ring retaining groove in a shaft. The tool comprises a flat, rigid body having a head at one end with an aperture extending therethrough. The aperture is comprised of a front section and a rear section. The front section is defined by a pair of spaced apart side walls joined by a curved front wall. The rear section is defined by a pair a spaced apart side walls joined by a curved rear wall opposite the curved front wall. The side walls of the rear section are spaced apart a lesser distance than the side walls of the front section, thereby defining laterally extending shoulders or ledges between said side walls of the rear section and the side walls of the front section. These shoulders serve as abutment members which engage the prongs of the snap ring to force the snap ring out of its retaining groove.
