Abstract
A tubular fence is made by fixing a vertical tube on a horizontal tube. A method of making the same is disclosed wherein an opening part is formed on the side of the horizontal tube. A pin having a large diameter remote end, a smaller diameter adjacent end, and a tapering connecting part is positioned in the horizontal tube aligned with the opening part or in the end of the vertical tube. As the end part of the vertical tube is inserted into the opening part, the end part of said vertical tube is caused to be expanded outwardly by press-fitting said vertical tube to said pin from outside, whereby it is held closely adherent to said opening part.
