ABSTRACT:
An apparatus, system, and method for the secure attachment and restraint of a pipe end within a fitting is disclosed. The invention includes a mechanical restraint apparatus that is integral and monolithic with the flange of a bell of a spigot-and-bell joint architecture, along with one or more internally disposed grooves within the bell that receive a circumferential gasket, in order to maintain a seal about the pipe end when it is inserted into the bell. The inventive apparatus combines features of mechanical connections and push-on connections.
