Fitting replacement Whirlpool Dishwasher heating element.

[elmo7sharp9]

Following advice on this forum,
I've traced the fault on my Whirlpool DWH B10 dishwasher to an open-circuit heating element.

I have sourced a reasonably-priced replacement part and am almost ready to proceed...

My questions are:

1)
Are the 2 slim metal rings that clamp the rubber hoses to each end of the heater re-useable ?

2)
What is the best way to remove/reattach these rings ?

They can slide off if ur good if not cut the raised bit off and get 2 new jubilee clips from a motor factors ie halfords.
