The present invention provides a quick connector made of plastics material for establishing a snapping connection between a tubular male part (50) and female part (40) of a fluid connection system. The connector has retaining means (10) adapted to be set within the mouth portion (41) of the female part (40) and having first and second flexing members (12, 22) for snapping engagement with the male part (50) and the female part (40), respectively. The first and second flexing members (12, 22) are provided at circumferentially spaced portions of the retaining means (10) so that the overall axial dimensioning of the retaining means (10) is reduced.
