  • Quick connector with tool release
    Patent number: 11885449
    Abstract: A quick connector for connection to a complementary counterpart comprises a coupling piece and a retainer for a section of a fluid having a coupling center axis defining an axial direction AD, a radial direction RD and a circumferential direction CD. The retainer is allocated to the coupling end, wherein the retainer has at least one retaining element for retaining the counterpart and at least one actuating element for opening the retainer for pulling the counterpart out of the coupling piece. The coupling piece comprises a first flange at the coupling end, wherein the first flange has a flange opening so as to insert a tool into the flange opening so that the tool can exert a force on the retainer and the actuating element, respectively. The flange opening has an outer border, wherein the outer border lies in radial direction RD outward of the flange opening.
