Abstract A sterilizable multi-part handle for attachment to a handle receiving fitting of a hospital surgery room light fixture is made of light weight, inexpensive molded plastic parts which are disposable after use, the handle including a handle body having a body grip portion and a threaded head portion to engage the fixture fitting and a disc separate from the handle which is provided with a central aperture via which the disc is assembled to the handle in a snap on fit connection between the handle body and disc. The exemplary connecting means includes a plurality of detents provided on the inner periphery of the disc aperture which snap into and seat within a disc receiving groove provided in the handle body head portion adjacent a disc seating flange against which the disc seats when the handle is turned into tight engagement with the associated light fixture fitting. A sterilized kit of handle parts is disclosed wherein a pair of nested handle bodies seat in side by side relation upon a pair of stacked disc with a retainer strap thereabout to hold the array in such preassembled compact relation within a sterilized peel back type package.
