               1. An aerator (1), comprising: 
            a housing (2), 
                a jet-splitting device (3), arranged or formed in the housing (2), configured to split an individual stream into a plurality of separate liquid portions, 
                the jet-splitting device (3) has at least two flow channels (4) which are oriented obliquely such that streams formed by the flow channels (4) meet each other, and 
                an insert part (5) is inserted into a hole (6) of a base body (28) of the jet-splitting device (3) such that the hole (6) is divided into the at least two obliquely extending flow channels (4), wherein the insert part (5) is fixed on the base body (28) by a retaining device (15) which includes at least one latching projection (17), formed on a surface of an inflow-side upper side (16) of the base body (28), that acts on the insert part (5) with a pretensioning force, 
                wherein the surface of the inflow-side upper side (16) is oriented in a cross-direction to a longitudinal axis of the aerator (1), and 
                wherein the at least one latching projection (17) projects inwardly from the surface of the inflow-side upper side (16) towards a center of the surface of the inflow-side upper side (16).
