That's a dastardly joke.

Drat, drat and double drat.

Simon,
Don't replace the "O" clip, just cut your pole hose just past the first section and put in a straight connector. To replace, remove the first section, disconnect the straight connector and replace the washer. Reassemble and happy days!

Yes. Have got a straight JG 8mm connector on each side of univalve now. You're right, it doesn't pull out. Works great. Thanks.

Hi Simon,
Sorry for the late reply, I've been away for the weekend! Glad you got it sorted, seems the easiest and most cost effective way to be able to replace the washers.

Another issue arose yesterday that I hadn't considered; the gritstop is no use if you use extensions.
