A lazy susan type device for holding food items has a top and a base that are snap fit to one another when the device is in use. The top and base can therefore be easily separated from one another to facilitate independent washing of those two parts. The snap fit device is a toroidal ring having multiple flexible “L”-shaped arms secured about the outer periphery of the ring. Each arm is momentarily displaced in a radially inwardly direction when the top and base are in the process of being interconnected to one another. The inherent bias of each arm causes each arm to abruptly return to a position of repose when the top and base are fully interconnected to one another. The displacement of each arm when returning to its position of repose is a radially outward displacement.
