In theory you could take it off once the bolts are tight.
Once the pinch bolts are tight it's pretty fricken' hard to get it off. Ever tried it?
IIRC even if you forget to torque the bolts (!) the safety catchy doobry prevents total destruction of crank. Maybe they lost that, too.

Nah, the "safety catch"(it's just called 'Plate' in the instructions) is just there to add friction to the clamp bolts, like a Nyloc, to reduce their tendency to loosen in service. If the clamp bolts have too little tension, the splined interface oscillates under load and since the axle is steel and the crank aluminium, the crank tends to get wrecked first.

yeah HTII.
Interestingly the plastic compression cap was missing but AFAIK that's only for compression prior to tightening the bolts. In theory you could take it off once the bolts are tight.
waits to be told I'm completely wrong
Anyway, bit of a shitter because he had to walk to the nearest station and take it up with Halfords as to why his Ultegra cranks have been destroyed.
