The fluid connector assembly includes a connector body with an intermediate portion that extends between opposite end portions and has a first bore. The connector body has an elongated wall that projects outwardly from the intermediate portion and that surrounds a second bore which opens to the first bore. A flat tube, which is made of a second material that is different than the first material and has at least one fluid passage, is in fluid communication with the second bore of the connector body. The flat tube has generally flat side walls and is lockingly retained with the connector body by male and female locking structures that cooperate with one another.
