In the same described embodiments, each thickened end portion includes a ferrule enclosing and crimped to the respective filament end, and a plastic body enclosing the ferrule and the respective filament end. The filament preferably includes a plurality of threads of high tensile strength coated with a low-friction material. In another described embodiment, a plastic material is injection-molded onto each end of the filament at a temperature greater than 280.degree. C. to melt the coating and to bond directly to the threads. A further embodiment is described in which the thickened end portion is constituted of a two-part bead having complementary socket and plug formations for firmly clamping the filament.
