ABSTRACT:
A concept for providing bands or rings which may be quickly and securely attached to plastic pipe as shown. The bands provide well anchored annular external flanges along the length of a section of pipe to facilitate coupling and sealing or to provide means for locating a pipe with reference to structures or devices. Rings that may be installed over the free end of a pipe and rings that may be opened to assemble over an already installed and coupled pipe are shown. Simple tooling for setting the ring is shown. This tooling is easily used in the field and in limited space, and may be hand operated.
