  • Two-piece split coupler for coupling large-diameter plastic corrugated pipe
    Patent number: 8967676
    Abstract: A coupler for coupling adjacent end portions of corrugated plastic pipe includes first and second arcuate members that cooperate with each other to surround and interfit with the corrugations of the plastic pipe. A stop member on one of the members enables the other member to be properly positioned over the other member when forming the coupler. Circumferentially aligned and spaced-apart attachment members resist relative movement of the two coupling members when backfilling the coupler and the pipes coupled by the coupler.
