Not sure whether they're the same things, but Wemoto do braided lines for the K series - I've got some, and they're great. Much cleaner than the originals.
You're right, the ends are jubilee-type clips as opposed to the original crimped type, but they're fine - especially when you realise that the original end joints (which you need to remove from the old hoses) have about half an inch of pipe that the crimps fit around. IIRC you'll need to cut the crimped sections off and then fit the ends into the braided pipes. Just use a dremel or something similar and take your time. The jubilee clips make fastening the new pipes in place a doddle - but just remember to put the heads of the clip adjusters at an angle you can reach when you fit the hoses to the engine so that you can tweak them if they're not quite tight enough.
And work on one hose at a time. The ends are different and you don't want to get them confused!
HTH.
