A push-fit connector for joining two fluid lines (1, 4), one of which is provide d with a retaining rib (2), has a sleeve (5) with radial apertures (12, 13), a latching device (6) with retaining arms (18), which can be pushed into the sleeve (5), provided with hooks (20) for gripping behind the retaining rib (2) and a radially external inclined surface (21). When the sleeve (5) and latching device (6) move apart, the inclined surfaces (21) are compressed against a front edge of an aperture (12) receiving the hook (20) in an axially displaceable manner, so that She hook (20) stays correspondingly more tightly engaged with the retaining rib (2) When the latching device (6) and the inserted fluid line (1) are pulled apart, a radially internal inclined surface ( 23) of the hook comes into contact with the retaining rib (2) so that the retaining arms (18) are spread apart and make uncoupling possible. In order to facilitate uncoupling, the latching device (6) has an unlatching arm (19) between at least one pair of adjacent retaining arms (18), which arm projects outwards through the aperture (13) in an axially displaceable manner.
