  • Patent number: 5303963
    Abstract: A fluid connector comprises a pair of retainers, with a first retainer having a pair of resilient legs extending axially and radially inwardly from an axially outer portion of a housing bore. The first retainer abuts a first upset portion on the tube to secure the tube within the housing. A secondary retainer is positioned axially outwardly of the first retainer, and has legs which also abut a second upset portion on the tube also securing the tube within the housing. The secondary retainer legs preferably extend parallel to the axis of the tube, such that they provide a strong resistance force against pull-out of the tube.
