ABSTRACT:
A connector for a liquid tight, flexible electrical conduit formed of a plurality of interlocking, thin, arcuate metal ring sections having an interior wall of alternating ridges and grooves. The connector includes a ferrule end insertable into the conduit with a plurality of spatially separated arcuate segments matching the conduit grooves for threadable engagement. A resilient seat member snug fit onto the ferrule is engaged by the conduit end as the conduit is threaded onto the ferrule to sealingly terminate the full perimeter edge of the conduit end, thereby enabling the conduit and connector assembly to be air and liquid tight. One or more ramp formed barbs are provided on one or more of the ferrule arcuate segments to lock and secure the connector on the conduit and prevent undesired loosening.
