Abstract
In a high pressure washing apparatus with a spray handle and a flexible hose leading to it, in order to create the possibility of rotation between the hose and the spray handle, it is proposed that the spray handle should display a barrel, for connecting to the hose, into which can be inserted in sealed fashion a hose nipple connected to the hose end, that a bearing surface be provided on the spray handle, against which rests a flange connected with the hose nipple, and thereby preventing the hose nipple from being pulled from the barrel, and that the bearing surface and/or the hose nipple flange surround the hose nipple in ring form, and be rotatable with respect to one another around the longitudinal axis of the hose nipple.
