I have found that the type of clamp on my heater hoses are in fact the
Rotorclip brand of CTB hose clamp. These are not the wire type - but the
flat steel band type. After messing with them for a bit, I discovered
that a pair of vice-grips works handily to open them up. The spring
tension in them is extremely strong so I wonder whether or not they
could reasonably be considered for reuse. It appears to me that the only
action one could take with these is to squeeze them to open for
positioning and simply release them to allow that spring tension to
close back and clamp any hose sufficiently to seal. Not much else one
could do.
