An automotive crankcase drain plug retainer is formed by placing a relatively thin washer around the drain plug, between its head and the adjacent surface of the crankcase. A permanent magnet mounted in a casing is connected with a radial tab on the washer by a flexible element. The casing magnetically contacts a crankcase to be drained, having the washer previously installed on its drain plug. The flexible element suspends the drain plug and washer when removed from the crankcase.

A retainer for supporting a bolt-like drain plug removed from a metallic liquid container, comprising: a U-shaped length of magnetizable channel having a flat bight portion and opposing parallel legs and having a longitudinally projecting tab portion at respective ends of its bight portion, said tabs being characterized by outwardly converging side edges terminating in an arcuately curved edge having an aperture adjacent the curved edge; a permanent magnet having adjacent planar surfaces flatly contacting the inner surfaces of the channel bight portion and its legs; a flat washer, relatively thin when compared with its outside diameter, and having a central opening capable of closely surrounding a drain plug adjacent its head end, said washer having a radially projecting apertured tab; a chain extending between one said channel tab and the washer tab; an endless ring extending through the aperture in said one channel tab and the link at one end of said chain; and, a part circular open hook having a closed loop at one end linked with the end link of the end of said chain opposite said one end, the end portion of said hook opposite the closed loop being removably received by said washer tab aperture.
