ABSTRACT:
44A clip for securing a handle shaft in a shaft-receiving opening in a tool is disclosed. The clip comprises a central portion and a tab portion integral with the central portion to project through a radially-directed slot in the structural portion of the tool which surrounds the shaft-receiving opening. One or the other of the central portion or the tab portion is configured for positioning on the interior of the structural portion of the tool which surrounds the shaft-receiving opening, and the other on the exterior. A flange depends from the central portion. The flange has an elongated aperture through which the handle shaft passes. The edge of the aperture remote from the central portion, preferably provided with teeth, is angled and biased towards the handle shaft to anchor it. Instead of the apertured flange, a tongue depending from the central portion and angled and biased towards the handle shaft may be used. The interior one of the central portion and the tab portion preferably includes at least one axially disposed ramp of narrow thickness, each ramp increasing in height in the direction of insertion of the handle shaft. Each ramp may have a radially disposed end face for anchoring into the handle shaft. Preferably, there are two ramps, angling in towards each other as their height increases.
