ABSTRACT:
The invention provides highly deformation resistant Lessing rings made in two parts. The first part comprises a metal strip bent into a ring shape with the contacting ends provided with projections and indentations which fit together to form a complete ring. The ends are held together using an anchor strut which has projecting tabs at both ends. The tabs fit into cooperating slots located in the projections at the ends of the bent strip and at the midpoint of the bent metal strip. The tabs are bent over to locate all parts rigidly in place.
