Strapkeeper ordered last Thursday arrived today. - works well 

That's a speedy delivery - I'm sure mine took a few weeks.

Pinegrove Leather do a similar thing that's 2 for £10.

That looks good and cheap too! I like the plastic C-clip on the Strapkeeper but I'm sure the Pinegrove Grolsh-washer-alternative would be good too

I got one of those Pinegrove ones, but I’m not convinced by its Grolsh washer approach - at least not with the endpin jack supplied with the K&K Pure Mini: the washer slipped off within an hour of me fitting it. It’s irritating that the initial design (the endpin jack), and the claimed solution are both flawed.

I saw the strapkeeper a few years ago, but being a. A tight northerner and b. Impatient I took a thick plectrum and fashioned a version of the plastic clip.
Find the dimension of your end jack at the thinnest point, drill a hole in the middle, then cut a channel just slightly smaller. Slides on after the strap and has been fine since.

Stop press! Pinegrove are GOOD.

I contacted them following the problem I mentioned above, and they sent me (for free) 4 new washers with smaller holes in them than the one initially provided; and with these the strap is now very secure on my K&K endpin jack.  

The explanation for the initial trouble I had is that, apparently, not all endpin jacks have the same diameter shafts and slots. Pinegrove slightly enlarge the hole in the washers they use because their experience has been that that suits most endpin jacks; but it seems the K&K one is best with the hole left untouched. 

Sterling service from Pinegrove in the end and I would recommend them - especially as they are now going to add a small leaflet to their product that clarifies the situation with regards to different diameters etc.
