1. A treatment element (14) for a treatment device (10), the treatment element comprising:
a housing (56) comprising:
a housing pot (58) having an annular outer wall surrounding a connecting axis (20) and extending from an open first axial end of the housing pot to a second axial end of the housing pot and surrounding an interior chamber of the housing;
a housing cover (60) closing the interior chamber of the housing pot proximate to the open first axial end, the housing cover comprising:
at least one inlet (88) for the fluid to be treated; and
at least one outlet (82) for the treated fluid;
wherein the housing cover is spaced axially inwardly away from the open first axial end of the housing pot;
wherein the treatment element (14) is configured to be connected to a connecting head (12) of the treatment device (10) by means of a releasable bayonet-type connecting device (34) through the execution of a rotational/plug-in movement about the connecting axis (20) of the treatment device (10);
wherein the releasable bayonet-type connecting device (34) on the treatment element (14) includes:
at least one housing connecting part (100) arranged at an axially outer side of the housing cover, the at least one housing connecting part (100) having:
an axially projecting wall section projecting axially outward away from the axially outer side of the housing cover;
a radially projecting wall section fixedly connected to the axially projecting wall section and projecting radially inwardly over the housing cover from the axially projecting wall section in a direction towards the connecting axis (20), the radially projecting wall section having:
an axially inner side of the radially projecting wall section forming an axially inner functional surface (106) facing the housing cover (60);
an axially outer side of the radially projecting wall section forming an axially outer functional surface (108) facing away from the housing cover (60);
wherein the axially outer functional surface (108) and the axially inner functional surface (106) extend helically about the connecting axis, the axially inner functional surface (106) and the axially outer functional surface (108) rising from a first circumferential end nearest the housing cover to an opposite second circumferential end spaced axially outward relative the first circumferential end;
wherein the housing cover includes an outer sealing ring arranged at an axial upwards or downwards distance of at most 5 mm beyond the radially projecting wall section of the at least one housing connecting part (100).
