Abstract
Abstract A drive belt with connector together with assembly tools for proper installation of the connector to the two open ends of a single portion of belt material. The main belt together with the flexible connector body are constructed of cord sections in various configurations and include in many embodiments a central spring member for adding strength and flexibility to the overall belt and means of connecting the belt. One tool is used to hold the respective ends of the main belt portion while the other tool holds the connector unit for engagement and connecting relationship with the two ends in order to form the overall completed belt structure.
