ABSTRACT:
The present invention teaches a simple and convenient hose end expansion device which slides within the hose end and is then quickly expanded by means of mechanical or hydraulic pressure, thereby stretching the hose end to a larger diameter. The device is then quickly collapsed and removed from the hose end, and a barbed coupling is inserted within the hose before it has sufficient time to return to its original diameter. As the hose returns to its original diameter, the hose coupling becomes secured within the hose end. External hose clamps may be added for increased security and safety.
