ABSTRACT:
A joint for pipes made of, particularly, mineral materials comprising a pipe, a sleeve to receive the pipe, and a gasket ring carried by the sleeve. The gasket ring comprises a guard ring and a flange ring, the guard ring being mounted in an annular tee-slot of the sleeve and the flange ring projecting radially into the sleeve. The sleeve is provided with an inwardly projecting inversion ring and with an annular chamber following the tee-slot, to respectively pivot the guard ring and then to receive it, when a pipe is inserted. The term "sleeve" signifies not only an enlarged pipe ending but also a cuff constructed to provide for the insertion of smooth pipe endings into both ends.
