ABSTRACT:
An elongated insert has an enlarged central area with wrench faces formed thereon. On one side of the central area, an end of said insert is formed to provide a connector. On an opposite side of the central area, the insert is an elongated pipe having a series of annular barbs formed thereon. An inner split collar fits over and is dog locked to the pipe after it is slipped into the end of a hose. An outer locking collar fits over the split collar, compresses, and secures it in place. Various principles are shown for selecting a degree of locking forces which optimizes and matches the ease of installation vs. the grip that is required.
