ABSTRACT:
A ring for the leak-proof and traction-resistant joining of the ends of two pipes which surround one another at a radial distance, made of a basic body of soft-elastic, resilient material having cylindrical contact surfaces engaging the pipes, and of a cone ring of unyielding material embedded therein, which is defined radially inwardly and outwardly by cone surfaces, in which cone ring the cone surfaces are inclined in the same direction and are at a distance from the surface of the oppositely-lying or confronting pipe which diminishes increasingly with increasing distance from its end.
