I think you'll find they are essentially the same thing, You might find C-clips only in the very small sizes. The larger sizes would need the additional stabilisation of the third tab thus making them E-clips.

Shoot me down in flames but that's just my two-penny-worth.

Buy quickly – they're gonna be banned…

S-O-D I like it I like it !!

CE?

I apologise Paul, it's a European in-joke!

I expect you've noticed laptop power supplies are plastered in icons:

Very few know what any of these marks mean, except for the one in red, which is controversial over here. Many Brits believe it's evil: 'China Export' and the threat of unbridled European Federalism. Popular opinion wants CE Marks to disappear when the UK leaves the European Union at the end of this year.

My example label on an internationally sold power supply just means the seller asserts the product meets relevant European Standards, just as he also claims it complies with FCC Part 15 Rules in the USA. Like C and E clips, the label has nothing to do with politics and Trade Deals.

What to do next about CE Marks irritates Brits who wanted to stay in the EU because having to replace them with a similar system wastes time and money. At the same time zero progress getting rid of the vile symbol angers those who voted to leave because it's becoming apparent one of their cherished goals probably won't be delivered.

Everybody is cross, ha ha! Unfortunately for me jokes that have to be explained aren't funny!
