ABSTRACT:
Improved self-tightening clamp assemblies are designed for application to the adjacent ends of connected pipe sections in spanning relationship to the joint therebetween. The assemblies include a plurality of clamp bodies configured for placement about the adjacent pipe section ends and carrying a plurality of pipe-engaging teeth; a clamping mechanism is operably coupled with the clamp bodies to cause the teeth to grippingly engage the pipe section ends. The teeth are oriented so as to exert an increasing gripping force on the pipe sections ends in the event of relative separation movement between the ends.
