ABSTRACT:
A union device comprises a body having an inner bore communicating with an enlarged annular opening in a face of the body. A separate annular piece is secured in the opening with a press-fit by means of an external barb on the piece which opposes removal of the piece. The piece has an oppositely directed internal annular barb which engages in the outer surface of the end of a press-fitted flexible tube to tightly secure the tube without constricting its inner passageway which communicates with said bore.
