Zusammenfassung:	A joint (20) is disclosed for connecting extruded segments (16, 18) to form a container (10), such as a pressure vessel for storing liquid propane. In cross section, joint (20) includes a pair of symmetrical tabs (22), each tab (22) configured at the end of adjacent arcuate outer wall segments (16). Tabs (22) are configured for contiguous engagement to form a boss (28) having a proximate neck portion (30) and a distal body portion (32). Joint (10) also includes a retaining member (40) configured at the end of an internal web segment (18). Retaining member (40) is configured to capture boss (28). A sealing weld (28 ) is utilized to seal the adjacent tabs at exposed seam (24).
