Abstract

A reusable end fitting may be attached quickly and easily to a hose without requiring production machinery. The end fitting has a first part with a collar which grips the hose against a second part with a barbed end. When two wrenches are used to turn one part onto the other part, a pilot end of a hose is gripped and pulled onto the barbed end. One embodiment provides a collar with springlike qualities that compress the hose against the barbed end. Another embodiment has threads inside the collar to propel the hose onto the barbed end.
