ABSTRACT:
A clamped assembly comprising one or more clamps securing tubes or tubular members together has the clamp or each clamp formed of two parts securable together, the clamping parts having a regular array of surface singularities, e.g. protruberances, which engage with a complementary array of singularities, e.g. dimples, on the tube or tubes so that, in the assembly each tube is positively located and firmly held without relaying on a frictional grip. The arrangement is particularly applicable to the jointing of tubes to form a pipe line, two tubes being joined end-to-end with a seal between or around the joint.
