Abstract
A quick connect coupling assembly comprising a housing having an internal passage divided into a large entry end and a reduced diameter, coaxially aligned smaller passage for receiving a tubing adapted to fit into said passages and to snap into fluid-tight sealing relationship with said smaller passage. The assembly includes an improved retainer for preventing disconnection of the tubing and, optionally, a perforatable dust shield for sealing the entry passage of the housing during shipment and handling prior to insertion of a tubing conduit, and after perforation by the tubing upon assembly, then seals the tubing in the housing entry passage. A subassembly comprising the housing, retainer and dust shield is also disclosed.
