Yes those eared clamp are what we use in industry on the operators pneumatic retracting air hose reels, because you cant tell the knuckle heads not to pull the hose out by only gripping the air gun, thereby putting all the load on the hose joint! they never listen as they are the fonts of all knowledge!
We find these types of clamp hold well due to their permanent crimped nature.
There are both double and "van Gough" single eared versions

 
you need special crimping pliers to crimp them and these come in single jawed
 
and double jawed with  side jaws for  space restriced applications
 
There are also pneumatic are crimping tools available.
