Patent attributes
A duct connection assembly suited to connect a thermoplastic fluid duct to a metal intake port. A connector housing is affixed to the end of the fluid duct and functions to releasable seal the fluid duct onto the intake port using an annular projection around the end of the port. When the port is inserted into the connector housing a snap lock connection is provided by a plurality of locking teeth that project inwardly through the housing from a collar to engage with the annular projection. Quick disconnect of the port from the fluid duct is effected by rotation of the collar with respect to the connector housing so that cam surfaces on the housing interact with the locking teeth to move the teeth radially outward to disengage from the annular projection.
