ABSTRACT:
A coupling is provided for the repair of flexible conduit, such as garden hose, comprising a body portion having at least one nipple for insertion into the free end of the flexible conduit. A slotted collapsible collet is radially compressed by a retaining nut thereby clamping the conduit between the nipple and the collet. The collet is generally frustoconical in shape and is reversible for retaining one size of conduit when disposed in a first direction and a larger size conduit when reversed. In order to accommodate a still larger conduit, the collet can be omitted. The body can include a second nipple which can be similarly attached to the free end of a conduit to effect repair of the conduit. Alternatively, the body can include a male or female fitting, a pair of which can be joined to effect repair of a conduit, or used separately in connection with other suitable fittings, as desired.
