Abstract
A barrier includes a housing having an interior surface and an opposing exterior surface extending between a first end and an opposing second end, the interior surface bounding a chamber that is adapted to receive a ballast. A coupler is rigidly connected to the first end of the housing, the housing and the coupler being separate discrete members that are connected together after formation. A structure, such as an opening or a post, is formed on the coupler for removably connecting a separate barrier to the coupler.
