Abstract
An oil drain plug is disclosed for cooperating with a socket in an oil sump. The plug includes a main body, an eccentric pin protruding from the main body, and an enlarged tip on an end of the eccentric pin. The socket includes a cup-shaped cavity having a lateral wall open at one end, closed at the opposite end by a bottom wall and including an internal surface for mating with the main body of the plug. The bottom wall includes an external surface facing outside the cavity, a through hole such that the enlarged tip of the plug extends beyond the external surface, and a slot departing from the through hole towards a distal end along an arched path centered in the axis and having a smaller width than the through hole for preventing the enlarged tip of the plug from passing through it.
