A system of flexible conduit and fittings useful particularly, though not exclusively, for conveying, supporting and connecting electrical service cables and wires. The system includes a corrugated, synthetic resin conduit which is flexible and mechanically strong, connector sleeves for clampingly engaging sections of the corrugated conduit in end-to-end relation, and hanger sleeves for clampingly engaging the conduit and suspending it from a wall or similar surface. A novel electrical outlet box is provided and includes internally toothed conduit-receiving inlet fittings for securely engaging an end of the conduits in inlets to the box.
