Abstract
A hand actuated, connect/disconnect arrangement is provided for the spray arms of a dishwasher. The spray arms are rotably mounted to a spindle having a cylindrical stem portion and a larger cylindrical spacer portion adapted to fit within the bore of a hub member in turn connected to the water supply. A tab segment extending inwardly in the bore and an ear section extending outwardly from the spindle are rotated into overlying contact with one another in a connected position whereby a washer is compressed to seal the hub and stem while preventing the ear-tab contact surface from inadvertently rotating to a disconnect position.
