ABSTRACT:
This invention relates to a lug for anchoring the end of a tie rod at a bell flange and spigot pipe joint and for sealing more effectively the bell flange and spigot joint. One portion of the lug is positioned on a bolt which connects the bell flange and a gland and is inserted between said bell flange and said gland. The other end of the lug is formed to hold securely the end of a tie rod. The tie lug is designed in such a manner that when the tie rod is tightly anchored to the lug, pressure is thereby exerted on the gasket between the bell flange and the gland with the result that a more effective seal is achieved.
