Abstract
A structure comprising two interconnected metal tubes used for supplying oil or air. The first tube inserted in the second tube has a tubular wall at its one end and an outwardly swelling circumferential wall formed inside the tubular wall. The second tube has plural slots arranged circumferentially. A seal member is sandwiched between both tubes. A binding band is wound around the slots to compress the portion having the slots, for fastening the tubes together.
