Abstract: A connector that is used to join a first modular barrier to a second modular barrier. The first modular barrier has a first frame element along one side with a first slot that extends along its length. Likewise, the second modular barrier has a second frame element along one side with a second slot that extends along its length. A flexible panel joins the two modular barriers together. The flexible panel has a first side edge and an opposite and parallel second side edge. The first side edge extends into the first slot of the first frame element and the second side edge extends into the second slot of the second frame element. The first side edge and the second side edge are enlarged and lock the first side edge and the second side edge into the first slot and the second slot, respectively.
