No, literally just wormed it. Had two go's where it started to look impossible. Then somehow on the third go it just came loose about the final bend (the tight one between the tops and drops). Can't remember whether the slot was on the inside or the outside of the curve.
Did attempt to lever it open a bit with an Allen key which worked a bit if i were to get it stuck, but I didn't seem to use it for fitting it round the bend.
Good luck. There are a few scuff on the bars now and some burrs on the stem from when for some reason the stem spontaneously tightened and became stuff, despite it being free just a second before. Much annoyance.
