A coupling configuration ( 1; 30 ) comprising a coupling element ( 3 ) and a supply capillary ( 2 ), wherein the coupling element ( 3 ) has a funnel-shaped section ( 5 ) which clamps an end ( 6 ) of the supply capillary ( 2 ), is characterized in that an envelope capillary ( 10 ) is provided into which the supply capillary ( 2 ) is inserted, wherein the end ( 6 ) of the supply capillary ( 2 ) projects past an end ( 11 ) of the envelope capillary ( 10 ), and the end ( 11 ) of the envelope capillary ( 10 ) is also clamped in the funnel-shaped section ( 5 ). The supply capillary is properly fixed in the coupling element and safely protected from capillary breakage.
