ABSTRACT:
A plastic electrical connector for connecting liquidtight flexible electrical conduit to an electrical component such as a junction box or outlet, comprises a plastic body and a plastic gland nut threadably attached thereto. The body includes a plurality of flexible fingers, each of which includes a collapsible section defined by plural, discrete hinges, the deformable section being bendable at each hinge. Gripping teeth are provided on the interior surface of the ends of the flexible fingers. The gland nut includes an inclined surface engageable with the flexible fingers for causing radial compression against the conduit. The gland nut further includes a pushing surface for engaging the distal end of the flexible fingers, which are preferably arranged in cantilevered form. Upon tightening the gland nut on the body, the gripping fingers engage the conduit, and as the collaspsible sections bend, the fingers axially move the conduit deeper into the connector for a liquidtight seal therewith.
