Abstract
Coupling for connecting the end of a hose or a pipe to an external threaded shaft includes a nipple and a coupling nut. The nipple has a bore extending along the length of its longitudinal axis and connects at one end to the end of the hose to be connected. An external annular groove is included and an external threaded segment is disposed adjacent such groove. The coupling nut has two end portions. A first end portion includes a first internal threaded nut segment disposed therein for threadedly engaging the external threaded segment of the nipple. A second end portion has a second internal threaded segment disposed therein for threadedly engaging the external threaded shaft. Moreover, an internal annular groove is disposed adjacent to both of the internal threaded segments of the nut for receiving the external threaded segment of the nipple upon insertion of the nipple in the coupling nut and after the external threaded segment of the nipple has been axially threadedly displaced past the first internal threaded segment. The external annular groove of the nipple receives the first internal threaded segment of the nut upon insertion of the nipple in the coupling nut and after the first internal threaded segment has been axially threadedly displaced past the external threaded nipple segment. Thus, the coupling nut is rotatably supported by the nipple.
