Claim 0:
1. A coupling assembly, comprising:
a female quick connector and a male member for insertion into the quick connector, wherein the quick connector includes a main body, wherein the main body has a coupling section for insertion of the male member into the main body, wherein the main body includes a hose section for connection with a hose or pipe, wherein the coupling section is connected to the hose section via a through bore of the main body, wherein the main body includes a face end which is allocated to the coupling section;
wherein the male member has a tip for insertion into the main body, a wall defining an inner surface and an outer surface, and a latching element on the outer surface of the wall, wherein the male member includes a sealing section between the latching element and the tip, wherein the male member has a longitudinal axis which defines an axial, a radial and a circumferential direction of the coupling assembly and the coupling section, respectively;
wherein the quick connector includes a retainer, wherein the retainer has at least one retaining element for interacting with the latching element of the male member for retaining the male member within the main body, wherein the retainer includes at least one actuating segment for actuating the retainer for unlatching the latching element and releasing the male member from the main body, wherein the male member is in a latching position when the latching element is latched onto the at least one retaining element, wherein the male member is in a pre-latching position when the retaining element overlaps axially with the sealing section of the male member;
wherein the quick connector includes a verifier, wherein the verifier is axially movable along a verification path, wherein the verification path comprises at least one locking position and at least one releasing position, wherein the verifier in axial direction is closer to the retainer in the locking position than in the releasing position, wherein the verifier is kept by the coupling assembly in the locking position when the male member is in the latching position, and wherein the verifier in the locking position limits a movement of a section of the retainer in radial direction, so that the retainer is not actuatable in the locking position of the verifier but actuatable in the releasing position of the verifier;
wherein the retainer is annular and the at least one retaining element is circumferentially spaced from the at least one actuating segment such that, in the pre-latching position, the at least one retaining element moves radially outwardly and causes the at least one actuating segment to move radially inwardly into a position that blocks rearward movement of the verifier.
