Connecting link, especially for tire chains

A composite connecting link for a tire chain made of two parts fixed together in which the complete link has a substantially smooth, continuously curved interior periphery, said link on each side being tangent about its circumference to a plane perpendicular to the axis of said link so that said link is of uniform axial thickness throughout its entire length, the first part of said link extending about a major portion of the circumference of said link and having a gap for receiving the ends of adjacent tire chain links, the second part having a section to fit in said gap between the ends of said first part and being symmetrical about an axial plane through its center, the ends of said two parts having complementary, interfitting ends, each end on one part having a pair of axially spaced legs having a total axial thickness of the thickness of said link, and forming a slot between said legs, the sides of said slot lying in planes perpendicular to the axis, each of the complementary ends of the other part having a projection formed with flat sides lying in planes perpendicular to the axis to fit between the flat sides of said slot, the ends of said second part having end surfaces at an angle to an axial plane and complementary surfaces on the first part to be engaged by the end surfaces on said second part and limit movement of said second part inwardly of said first part, and means through the interfitting ends of said parts to secure said parts together to form a complete ring, the uniform axial thickness of said composite link and the smooth, continuous internal periphery allowing a chain link connected thereto to move freely about said composite connecting link.
