Abstract: A tearable and disposable retainer for temporarily holding and positioning an apertured element such as a washer in place along the length of an elongated, generally cylindrical part. The retainer of the present invention includes a singular, generally planar member made from a manually tearable material. The retainer member defines a generally centralized hole or opening with a series of cuts or slits radially extending therefrom. A series of angularly shaped segments are defined between the slits, with each angularly shaped segment having a formed arcuate edge at a distal end thereof for frictionally engaging the outer cylindrical surface of the part over which the washer is loosely fitted.
