ABSTRACT:
An apparatus for joining the ends of a pair of ribbed ducts together has a collar with an interior suitable for receiving the ends of the pair of ducts therein, a first coupler element translatably secured adjacent a first end of the collar, a compressible seal disposed between a surface of the first coupler element and the first end of the collar, a second coupler element secured adjacent a second end of the collar, and a second seal disposed between a surface of the second coupler element and the second end of the collar. The coupler elements are translatable so as to compress the seal such that a surface of the seal will bear against a respective rib of the pair of ducts.
