Replaced it twice, figured when the batten sticks out further than the clew, that's what we get!
Anyway, this time I'm thinking about putting the batten rope over the tensioner screw trimming a little dip to keep it in place and call it a repair :D ! Thoughts?
If you just put the rope over the end you won't be able to apply enough tension. The camming action of the plastic bit applies all that pressure
Its NP . They regularly break . Super easy to replace . You just need a stash of spares , there all the same on all NP sails for the last many years . And because there NP , there will be many trashed sails around to get parts .
Over the years I've broken over a dozen .
^^^^
You know what's going to happen , now that you said that 
A few times , while sailing , Ive noticed a batten end sticking out of the sail . I don't over tighten .
Im probably a ham fisted clutz.

Never broken one, adjust with max out haul.
That sounds like a compromise, what if you want to let some outhaul off (adjustable) if sailing off the wind?
I never broke one and thought they were the simplest / best design for a no-tool adjuster
Then again, I tension battens maybe twice in the life of a sail. Racey types maybe do it more?

Letting out haul off? I thought we were talking about breaking the plastic batten tensioner clamp, presumably when adjusting them on dry land and more presumably when increasing the tension by screwing them outwards. I would have thought you'd be doing well to break one adjusting your outhaul 
my point was if you make the adjustment after increasing the outhaul you're putting less stress on that clamp.
You should only adjust the bottom 3 battens of a NP sail while the sail is unrigged.
Try a cable tie over clip and under batten.
I have a couple of spares you can have (I'm South of Brisbane) if want them PM me.
BTW- that sail 'going by colour in pic' is many years old

Did it break on its own or were you applying batten tension?
Either the power of the white water (got smashed) or the clip hit the reef.
The rest survived :D !Select to expand quoteMark _australia said..

It's possible when there's no tension in the sail. The rope can be pried over the batten screw.Select to expand quoteAUS4 said..

Two great tips!
Proper batten tension is generally tuned when the sail is fully rigged but... with the neilpryde clip design, it puts too much tension on the clip and I heard of people breaking them while force closing them rigged.
While when tension is released, they can be clipped shut much more easily. So one may need to add and release tension to fine tune adjustments.
Without a donor clip, I could zip tie the rope around the tensioner screw to keep it in place, maybe wrap the whole thing with some sticky tape to protect from abrasion...Select to expand quotemusorianin said..
Have you tried inner tube?
Funniest comment ever :D ! Sadly I couldn't seem to think of a way to use it here, you?
In the end, I had 3 spare clips, I figured my sail is on its last legs and will provide two more clips (3 battens only!!) as a donor for the next neilpryde (if I get one). So I sliced open one of my donor batten clip and we'll be replacing it again.
EDIT: Filling in the gap, gluing in a sliver of sorts, might increase its structural integrity to protect from future stress.
