Patent ID: 7950699

Claim:
A plug-type coupling for connecting two fluid lines, the coupling comprising: a coupling component having a housing, an opening and an adjacent receiving duct; a coupling piece inserted into the receiving duct, the coupling piece having a holding rib protruding from a circumference thereof outwardly and forming a locking surface, wherein the holding rib and a locking stirrup are configured to interact, wherein the locking stirrup has at least one leg which is resilient parallel to the opening; and a disassembly element formed as a sliding member linearly movable into the housing of the coupling component, wherein the disassembly element is configured to act on the at least one leg in an opening direction, wherein the locking stirrup is U-shaped with two legs and a base connecting the two legs, and wherein the disassembly element is mounted so as to be slidable in a direction extending perpendicularly to the base, wherein the disassembly element has at least one leg to positively engage the disassembly element in the housing, wherein the at least one leg of the disassembly element is arranged in the axial direction of the receiving duct outside of an area in which the leg is located, wherein the disassembly element is movable in a direction out of the coupling component up to a position in which the disassembly element is flush with the outer contour of the coupling component, and wherein the coupling component has a receiving space for the locking stirrup, wherein the receiving space is covered on a side opposite the disassembly element by a housing section, wherein the disassembly element has two inclined surfaces that interact with the locking stirrup.
