ABSTRACT:
The invention provides a generally cylindrical, releasable interlocking arrangement comprising a lower portion having an inwardly-directed rim at its upper end, and an upper portion having outwardly-directed resilient members at an outer periphery thereof. The two portions snap-fit into one another and are mutually rotatable. The second portion consists of a flexible ring-shaped element with the resilient members extending longitudinally and radially thereof, an outer element that receives the resilient members in slots in the outer periphery thereof, and a third element that engages with the outer element and retains the resilient members in the slots. The two portions of the interlocking arrangement may be secured within respective cylindrical housing parts of a grinding device, in particular a pepper mill, with a drive member of a grinding mechanism passing freely through the lower portion and engaging with the upper portion of the arrangement.
