A combination connector and supporting member for a segmented membrane barrier is disclosed. A tubular connector is joined to one end of a membrane segment along a continuous seam and a second smaller connector, adapted to fit within the tubular connector, is attached to the opposite end of the membrane segment along a second continuous seam. A projection, extending beyond the edge of the membrane segment is adapted to fit within a key or the like for supporting and locating the connectors in a trench.

A barrier for underground fluid material flow control comprising: a trench in the earth having a length extending across the expected polution path; a segmented membrane barrier in said trench, said barrier comprising a plurality of membrane segments; a first tubular joining member on one end of each of said segments, each of said first joining members comprising a tubular member attached to said segment along a continuous fluid impervious seam; said tubular members characterized by a preselected inside dimension; a second tubular joining member on the other end of each of said segments, each of said second joining members comprising a tubular member attached to said segment along a continuous fluid impervious seam; a slot in a side wall of each of said first tubular joining members adapted to pass said membrane therethrough when said second tubular joining elrments are disposed within said first tubular joining members; at least said first tubular joining member having an end portion projecting beyond said membrane segments; means in said trench for receiving said projecting portion for locating and supporting said second tubular joining member; a fluid impervious sealing material disposed in the space between said first and second tubular joining members.
