Abstract
A grommet has retention wings and a distal end of a barrel with pin retention pawls. The pin retention pawls include an inner retention tooth with a lead-in ramp surface facing toward the grommet head. A lead-out ramp surface is distal of the lead-in ramp surface and facing away from the grommet head. A pin includes a recess receiving the inner retention tooth, with a pin head facing surface positioned and designed to engage the lead-out surface and radially outwardly displace the pin retention pawls during removal of the pin from the grommet. A distal facing outer surface of the pin engages the lead-in surface and radially outwardly displaces the pin retention pawls during insertion of the pin into the grommet. A two-shot molding method of manufacturing is also provided.
