A plastic conduit for protecting and directing electrical and telephone cables, employing elongated barrel portions with lipped ends and a snap-on coupling collar. Partition walls intergral with the conduit walls are used to divide the internal passageway of the conduit section. The partition walls are contoured at each end to interlock with the ends of adjacent conduit sections to provide column-like support. Gasketed ends seal the joint between the conduit section and coupling collar. Flanged ends index the coupling collar and limit axial movement and deflection. Interrupted peripheral lips and an interrupted annulus within the coupling collar provide for differential flaring out of the collar ends and corresponding necking-in of the conduit ends as the two are telescoped together. The lipped edges are received within the annulus of the coupling collar and snap fit into position. The snap fitting lips lock the conduit section to the coupling collar. The coupling collar is reinforced within external ribs and has camming surfaces at each end to assist snap fitting the coupling collar onto the conduit ends.
