ABSTRACT:
A coupler for use in joining two pipes in a butt joint. The coupler includes a band clamp and a split sealing sleeve disposed inside the band clamp for encircling the abutted ends of the pipes. The split sealing sleeve has a tongue-and-groove sealing joint at the confronting free ends of the sleeve. The sealing joint has a member at the mating edges to provide a resilient interference fit of the tongue-and-groove.
