Abstract
On the inner surface of a rubber hose body, a laminated hard resin layeris formed to constitute a barrier layer that is impermeable to fluids. A clamping connection is made to hoseby a clamping member, which clamps the hose body to a companion pipewhen the companion pipe is inserted into the hose body. The layeris not laminated over the entire axial length of the hose body but instead leaves an end part exposed. An annular groove is formed at the endof the layerabutting the end part of the hose. An elastic impermeable material is placed in the groove which is compressed by the pipe upon insertion. The companion pipehas a protuberancewhich rests at a position between the endof resin layerand the clamping member so that a seal is formed by elastic compression of the outer surface of companion pipeagainst the end part of the hose.
