ABSTRACT:
Disclosed herein is a compound joint in which a lower section and an upper section are mated along a common contact plane. Means for positively interlocking the sections are provided in each section. A depressed area on the surface of each of the sections is oriented along the common contact plane, such that when the sections are interlocked, the depressed areas form an enclosed tube. A spreader tube can be positioned within the enclosed tube, whereby the expansion of the spreader tube within the enclosed tube to a volume larger than the volume of the enclosed tube causes said interlocked sections to be permanently joined.
