Aluminum Cam & Groove Coupler, Female Half, 2-1/2 Inch ID Hose Barb

Interchangeability is a key feature. It's designed to work with any product made to A-A-59326 (which used to be MIL-C-27487F) or DIN 2828 standards. Just a heads-up though, the 1/2" and 8" sizes sometimes don't play well with other brands.

Cast-in lugs on the female coupler body let you slide a safety pin through once the adapter is fully seated and the cam levers are locked down. Until that pin is pulled out, the levers physically can't lift, so the connection won't release on its own or by accident. When you're ready to disconnect, pull the pin, lift the cam arms, and the adapter slides right out. It adds maybe two seconds to the process but keeps things from popping loose under pressure or vibration.
