In case there's anyone who didn't already know this: the Chrysler-type
spring-wire hose clamps are inherently superior to the screw-down
clamps, because, as long as the spring-wire guys are not defective, and
are properly size-mated to the subject hose , they will continue to
exert pressure onto the hose, due to their natural compression
characteristics.
The screw-down guys can, and routinely do,
fail, over time, when they fail to maintain their compression against
the hose, when the hose shrinks/hardens with age, and/or due to the
failure of the screw-down mechanism, itself, or due to the
screw-mechanism not being sufficiently tightened-down, to begin with.
The spring-type hose clamps do require the use of a dedicated wrench,
but they are available over the counter at parts shops, and, the
later-versions (like the one I have) have a neat one-way ratchet, like
a Vise-Grips, where you can set the degree of compression that you want
the wrench to hold, as it grips (holds-open) the spring clamp, as you
maneuver it over/around the hose.

You
haven't live until one of the original type heater hose clamps lets a heater
hose slide off at 6000 RPMs and hoses the distributor down and short it
out so that it makes the engine backfire and all the steam in the world comes
out from under your hood.
I did that while test driving one of the very first production cross-ram
Dodges, out of engineering. What really adds to the pleasure is that it
was about 20 degrees outside. All that steam, and the heater won't work!
