A connector for connection between two fluid-conveying elements, in particular for connection between two motor vehicle pipes, with a female plug-in part and a male plug-in part which is insertable into the female plug-in part. A retainer is connected to the female plug-in part, the retainer allowing the male plug-in part to be fixed, in the inserted state, to the female plug-in part. The retainer may be pivoted from an open position to a fixing position—and vice versa—about a pivot axis arranged in the region of the outer surface of the female plug-in part.
