For starters I say forget those spring clamps.
The work fine for new cars and parts at the factory.
Otherwise...
The 'right' ones to use are german, stainless, have slightly turned up edges
so they don't dig in to the hose, and have a 6 mm hex on them.  ( using a
screwdriver is not sufficient, needs to be tightened with a quarter inch
drive socket.  )
  Iv'e had some hose junctions that just would not seal........but I sure
wouldn't use spring clamps.  They are practically dangerous !

Subject: coolant leak oil cooler to water pump

Dear listees,
has anyone found a good solution for the connection
from the oil cooler to the top of the water pump? My
syncro engine has a hose elbow, a section of metal
tube and another straight hose section there. Pretty
complicated, four clamps, hardly accessible right next
to the exhaust. I can't get the connection of the
elbow to the pipe to stop leaking. I already have new
hoses, cleaned the tube, put spring clamps on. Still
leaking. I guess being so close to the exhaust gives
it a pretty high heat load. Any good solutions to
this? Or am I missing something simple here? I would
like to put something in plave that is absolutely
bullet-proof. I don't like coolant leaks out in the
woods.

Reinhard
