A tube-to-hose coupling includes an elongated hollow insert connected between an end of the tube and defining an insert receiving portion and the end of the hose defining an insert receiving portion. The insert is disposed in the insert receiving portion of the tube end and the insert receiving portion of the hose end in fluid tight sealing relation. Thermoplastic polymeric material is bonded between the insert and the hose during insertion of the insert into the bore of the hose. The tube is connected to the insert and the hose by plastic deformation. In one embodiment the polymeric material is a layer defining the internal bore of the hose. In another, the polymeric material defines an outer layer on the insert.
