A poultry watering device, connectable to a water supply line for supplying water to the poultry, comprises a cup integrally formed with a sleeve, a valve including a valve body receivable within the sleeve, and a valve operator disposable within the cup and engageable by the poultry to replenish the water supply to the cup. Bayonet-pin and socket connecting elements join the sleeve and valve body facilitate quick attachment of the cup to the valve by rotating the sleeve with respect to the valve body. Either the cup or the valve includes a projection engageable with a part of the other to restrain the rotation of the sleeve with respect to the valve body, and thereby to prevent detachment of the cup with respect to the valve by the poultry.
