ABSTRACT:
A tube is insertable into a housing and secured by a collet connector. The tube has a first upset portion for actuating the collet and a second upset portion outwardly from the first upset portion. A retention clip has a first pair of arms which attach to a portion of the housing and a second pair of arms which attach to the tube outwardly of the second upset portion to further secure the tube within the housing. The end of each of the second pair of arms include a ramped surface. If the tube is not fully inserted within the housing before attaching clip, and thus the first upset portion has not fully actuated the collet, the ramps will cam along the second upset portion, thus pushing the tube into the housing and likewise the first upset portion through the collet.
