Abstract
A pair of similar U-section clips each have a pair of legs secured to a respective belt end and a plurality of spaced knuckles that are interleaved to form a transversely extending passage. A coupling rod extending through the passage and interconnecting the clips has a relatively soft and bendable core pin and a helicoidal wrap of a wear-resistant hard material surrounding and directly engaging the pin and engaging the clip knuckles. The wrap can be made of an austenitic manganese steel and the pin can be a length of highly flexible steel cable.
