Just bought these gizmos.
I cannot beleive i am asking this, but i have been trying every possible thing you can with them.

They are used in conjunction with Speedfit fittings (older non-locking style only I think) to prevent the release flange (or whatever it's called) from being pushed in (for example by pressing against a joist). I presume they clip over the flange. Shouldn't be necessary in most cases.

Chris, i assumed exactly the same thing, but they do not fit onto anything at all

 

[chrishutt]

Which type of speedfit fitting are you using? If the newer type with locking nuts, they won't fit.

 

[breezer]

put them on ebay as ever lasting ring do - nuts

 

[wilhelm]

good idea

Used some on friday but used them on the older fittings as said the newer fittings twist and lock to stop the fittings pulling apart http://www.speed-fit.co.uk/part_spec.asp?s=PKM19_S1they also do them in different colours may be possible the older collet covers are not suitable on the newer push fittings and scewfix have got old stock?

You'll find what you need on page 6 of this
