A simple hinge is defined from a single-part component which is used in pairs as hinge halves which mutually engage to define a tough, long-lasting hinge. The hinge pin, and hinge sleeve which engages the pin, are in effect separated into component lengths defined on alternate sides of the hinge line on the respective hinged halves so that each hinge half defines a portion of the entire pin and a portion of the sleeve. These sleeve/pin lengths engage the pin/sleeve lengths of the identical, but reversed, mating half. In one important form, the hinge sleeves are helically cut to interstitially engage ribs defined on the pin segments so that the sleeve halves axially migrate as they rotate about the hinge axis, forming a self-closing hinge.
