• an adapter (4) removably inserted into the housing, the adapter (4) defines a flow path (5), the adapter (4) is arranged in the jet former receptacle (3) so as to be rotatable between a fixing position, in which the adapter (4) is locked with the housing (2) and forms a flow resistance in the flow path (5), and a releasing position, in which the adapter (4) is removable from the jet former receptacle (3);
• the adapter (4), in the fixing position, is locked with the housing (2) on an outer side (8) of the housing (2), and is released by a rotation of the adapter (4) into the releasing position;
• the housing (2) has a noncircular contour (10) on the outer side (8) thereof at least in one portion (9);
• and
• a detent connection between the housing (2) and the adapter (4), the detent connection including a detent element (13) on one of the housing (2) or the adapter (4), and a counterpart detent element (15) on the other of the housing (2) or the adapter (4), the detent connection being configured such that a rotation of the adapter (4) relative to the housing (2) forces the detent element (13) out of engagement, or releases said detent element from engagement, with the counterpart detent element (15).
