This hose is held on to the pump with a crimped metal collar. By carefully prying up the crimped indentations with a small screwdriver, you can pull the hose out of the collar, preserving the collar for future use.

The jagged edges on the end of the pump body help to secure the hose. The crimped metal collar adds additional security when pumping at high pressure.

After removing the crimped metal collar, use small pliers to smooth out the crimp marks so the collar slides easily onto the end of the hose.
