A member posed this to me in a PM

Sir my XT 60 connectors are too tight what should I do??
Is there a lock mechanism?? Huh?

Well, they are meant to be tight! You sure don't want them to open up in mid-air!

Get used to them. With some use they ease of a bit. And, with some practise, you will be able to open them with one hand

Try pressing the edges of the female part then pulling them apart

Thank you sir...
