Abstract: A spraying device comprising a spray nozzle holder mountable in a holder housing and having two mounting elements extending in opposite directions from the nozzle in the holder and transverse to the housing, one of these elements being a rotatable handle. The housing has two openings located substantially opposite each other for accommodating the respective mounting element; at least one opening having a width which is less than the width of the holder in the vicinity of the nozzle, and at least one slot-shaped opening along which the holder can move crosswise to the housing when the holder is being mounted in the housing or dismounted therefrom.
