A double wall safety hose delivers water from a standard threaded hose bib to an appliance or plumbing fixture. The apparatus includes an outer and an inner hose that extends through the outer hose. The inner hose is communicably attached at each end to respective threaded connector. A closure in the form of a ferrule or bushing surrounds and sealably interengages each end of the inner hose. A corresponding end of the outer hose sealably interengages an enlarged outer surface of the ferrule. This seals each end of the safety hose apparatus so that water leaking through a rupture in the inner hose is retained within the outer hose. A drain port attached to the outer hose discharges water that has leaked from the inner hose to a drain line.

1. A safety hose apparatus for delivering water from a threaded spout of a standard hose bib to a standard threaded appliance inlet, said apparatus comprising:a continuous outer hose; an inner hose extending through said outer hose; and a pair of end fittings respectively attached to corresponding ends of said inner and outer hoses, each end fitting including an interior tubular element to which a corresponding end of said inner hose is attached, a threaded connector rotatably attached to said tubular element and threadably engagable with a respective one of the threaded spout and threaded appliance inlet, and a closure attached to and generally annularly surrounding said tubular element, said closure including a generally radial shoulder; the corresponding end of said outer hose carrying a radially inwardly turned lip having a diameter that is less than an interior diameter of said outer hose, said lip radially overlapping and interengaging said shoulder to secure said outer hose to said closure, whereby water leaking through a rupture in said inner hose is contained between said inner and outer hoses.
