ABSTRACT:
A quick connect/disconnect coupling that eliminates the need for tools and the tedious loosening and tightening of hose clamps when detaching and reattaching hoses, such as dust collection system hoses, between machines. The coupling includes a first fitting adapted to be secured to a machine such as a debris generating machine or a dust collector, and a second fitting fixedly secured to a longitudinal end of the associated hose for being partially engaged with and locked to the first fitting. The fittings are preferably translucent or clear so that debris flow can be observed.
