Abstract: A driving belt formed from detachable, flexible, elongate links arranged in a staggered, overlapping relationship. Each link is provided with a stud which is rotatable relative to the link and has a head which is shaped to pass through perforations in other links when the head is orientated correctly relative to the perforations but not otherwise. The arrangement allows simple assembly and disassembly of the belt without any lateral distortion of the material of the links.
