A fluid coupling for fuel lines in motor vehicles, includes a housing having a receptacle for a counterpart, a blocking member in the receptacle and engageable behind a blocking rib of the counterpart to fix the counterpart in the receptacle, and a detection sleeve axially movable in the receptacle, and having a first engagement portion, which engages with the blocking rib to move the detection sleeve axially into a detection position, and at least one second engagement portion arranged behind the first engagement portion and, when the counterpart is pulled out, engages with the blocking rib to move the detection sleeve out of the detection position, into the initial position, and the detection sleeve includes at least one detection portion (64), received within the receptacle in the initial position so the detection portion is not visible from the outside and, in the detection position, visibly protrudes from the receptacle.
