A fixing element is provided for fixing a household appliance to a part of the kitchen cabinetry, which is adjacent to the household appliance. The fixing element is configured as a fixation lug and is disposed between the household appliance and the part substantially at least over the total height of the part of the kitchen cabinetry. A compact fixing element is thus obtained, which permits a precise, stable, easy and economic fixation of the household appliance into an opening in the kitchen cabinetry. Another advantage of the lateral fixing element is the clean and pleasant aspect thereof. Moreover, flexible use of only one type of fixing element is possible, due to the fact that the element can be used independently of the counter top material as well as in case of elevated mounting of the appliance or in case of a cutout counter top.
