ABSTRACT:
A connector for connecting to helically corrugated conduit comprises a bolt member having a passageway therethrough and a connector body having a hollow end portion that receives the bolt member. The connector includes a collet clamp within the passageway that has a grooved gripping surface adapted to be received within the helical corrugations of the conduit. The collet clamp includes a plurality of fingers each having a radially inward directing gripping surface and a wedge-shaped outer surface. A bushing having a frustoconically shaped bore is advanced over the fingers of the collet clamp when the bolt member is attached to the connector body in order to force the fingers radially inward into gripping contact with the corrugated conduit.
