The conduit system includes a connector fitting joining adjacent ends of a pair of the corrugated plastic conduits in end-to-end relationship, a junction box inlet connector joining one end portion of the corrugated plastic conduit in an opening in one wall of a junction box, and a switch box inlet fitting joining one end portion of the corrugated plastic conduit in an inlet opening in one wall of a switch box. Both the connector fitting and the switch box inlet fitting include a pair of hingedly connected semicircular clamping elements each including integrally molded rib members and including locking means on the opposite side from the hinge member with both the locking means and the hinge member being embedded in opposite sides of the clamping elements so that they do not extend outwardly from opposite sides thereof. Both ends of the connector fitting are identical while one end of the switch box inlet fitting has concentric interior and exterior surfaces for adhesively securing the same in the switch box. The junction box inlet connector includes a pair of semicircular flat snap ring elements adapted to be inserted around the depressions in the plastic conduit at opposite sides of an opening in the wall of the junction box to maintain the end portion of the plastic conduit in position in the junction box.
