A plug-in coupling for fluidic systems, in particular for CO<SUB>2</SUB>- and fuel-conducting systems, including a housing ( 1 ) and a plug ( 2 ) which can be inserted into the housing ( 1 ). The plug ( 2 ) can be inserted by a plug stem ( 3 ) into a receiving opening ( 4 ) of the housing ( 1 ) in a manner sealed by at least one circumferential seal ( 5, 5 a , 5 b) and, when inserted, it can be locked therein against release by a locking device having at least one latching element ( 7 ) arranged on the plug ( 2 ) and a latching shoulder ( 8 ) interacting with the latching element ( 7 ). The housing ( 1 ) has two-part design with an inner housing part ( 1 a) and an outer housing part ( 1 b), which can be connected releasably to the inner housing part ( 1 a) so that it essentially surrounds the inner housing part ( 1 a). In order to install it without destroying it, the latching shoulder ( 8 ) is formed at one end in an entry region ( 4 a) of the receiving opening ( 4 ) on the outer housing part ( 1 b).
