Mounting assembly for mounting a spray head ( 4 ) to an opening of an over 10-mm thick wall. The mounting assembly comprises a holder ( 1 ) for receiving the spray head ( 4 ) and a clamping piece ( 6 ) which comprises threads ( 7 ) for engaging threads ( 2 ) in the holder ( 1 ) and it can be moved axially in relation to the holder ( 1 ) and an expansion means ( 11 ) supported by the holder, the clamping piece ( 6 ) being arranged so that movement thereof causes movement of the expansion means ( 11 ) from its zero position, in which the diameter of the expansion means has a first value, to a fastening position, in which the diameter of the expansion means has increased to a second value for pressing the expansion means against a wall of the opening. The invention also relates to mounting assembly for mounting a spray head to an at most 30-mm thick wall.
