Abstract
A hose coupling is provided primarily for irrigation applications and features a quick-connect capability ideal for use with the flexible irrigation systems such as are used on sugar cane plantations and elsewhere requiring relatively frequent assembly and dismantling of the system, the coupling being characterized by a tubular body portion having a nipple over which a flexible irrigation hose is pulled, there being a collar on the connector body which by virtue of a pair of helical ramps is forced over the end of the irrigation hose locking it onto the nipple when the collar is twisted. Being unrestrained other than by the helical ramp structure, the collar can be pulled axially to directly engage the irrigation hose, or twisted to utilize the mechanical advantage inherent in the helical ramps so that dual alternative operative modes are inherent in the design.
