Abstract
A connector for connecting to helically corrugated conduit which comprises a bolt member having a passageway therethrough and a connecotr body having a hollow end portion for receiving the bolt member, In addition, the connector includes a helical spring within the passageway which is adapted to be received within the helical corrugations of the conduit. The connector further includes a means for forcing the bolt member into the hollow end portion of the body of the connector to squeeze the spring between the bolt member and connector body whereby the spring is axially forced against the corrugations. In addition, a method of connecting a helically corrugated conduit to a connector is disclosed which comprises the steps of (1) sliding a hollow bolt member having an internal flange over an end portion of the conduit until a part of the end portion closest to the end is uncovered; (2) screwing a helical spring onto a part of the uncovered end portion of the conduit until the entire spring is within the corrugations of the conduit; (3) sliding the bolt member axially over the spring until the internal flange of the bolt member contacts the spring; and (4) forcing the bolt member into a hollow end portion of the body of the connector.
