ABSTRACT:
A release sleeve used with quick connect tube connectors includes a plurality of planar surfaces at an outer peripheral surface which bias retainer legs radially outwardly to allow removal of a tube. The use of planar surfaces provides a greater contact area than prior art release sleeves, thus reducing the amount of force necessary to allow tube removal. In a further feature of the present invention, the release sleeve has grooves at an outer peripheral surface which allow passage of indicator legs such that the release sleeve may be used in combination with an indicator used to give an indication that a tube is fully connected.
