ABSTRACT:
A quick connect coupling generally comprises a housing having an axial bore extending inwardly from an entrance and increasing in diameter moving into the housing. A tube has a tube bead of increased diameter spaced from an inner end of the tube and is insertable into the bore. A generally annular radially expandable collet disposed within the bore expands upon insertion of the tube and contracts onto the tube outwardly of the tube bead. The collet functions as a wedge between the tube bead and the increasing diameter portion of the housing, thereby retaining the tube within the housing. In one embodiment, a spring disposed within the housing biases the collet toward the entrance of the housing, ensuring proper position of the collet in extreme conditions. The inventive collet allows smaller tube bead diameters to be used.
