ABSTRACT:
Connector means for use in connecting a corrugated conduit, of the type having longitudinally spaced-apart circular ribs on at least its outer surface, to an electrical box or other members. The connector means, in one embodiment, employs a tubular element on the box and the tubular element is provided with a slot. The conduit is axially inserted into the tubular element. A wedge is wedged in the slot so as to project into a groove between two adjacent ribs on the conduit to secure the conduit in the tubular element. In another embodiment, the connector means includes a wall in the box having a hole through which the conduit is passed. A wedge is inserted in the gap between the wall edge defining the hole, and the conduit, to lock the conduit in place.
