Can anyone identify this part please.

I purchased a Shark liftaway from our local recycling centre, it was absolutely filthy and needed taking totally to pieces and cleaning, on the main powered floor tool it was blocked and also hair grip and pencil stuck in duct hose sideways which was split. 3 months elapsed between disassembly and sourcing a new hose so we have managed to get it mostly back together but we cannot remember where a couple of items went. 2 resemble a little burgundy key type shape, the others are little metal rods. Any help greatly appreciated.
