Abstract
A quick connect coupling having a self-contained releasable collet generally comprises a housing having an axial bore extending inwardly from an entrance. The axial bore includes a large diameter portion adjacent the entrance. A tube having a bead of relatively large diameter is insertable into the bore. A generally annular radially expandable collet disposed within the bore of the housing expands upon insertion of the tube into the housing and contracts onto the tube between the bead and the housing, thereby retaining the tube within the housing. The tube is selectably releasable from the housing by an annular pilot disposed within the housing having an inclined surface complementary to an inclined surface on the collet. Release members are provided to facilitate axial inward movement of the collet into the housing. The collet then rides up the inclined surface of the pilot, thereby radially expanding the collet and releasing the tube from the housing.
