Small corrugated black pipe in compartment for leisure battery under the wardrobe loose

[Jennie]

Hi.
Took the Leisure battery under the wardrobe out for the winter (will not do that again) While replacing the battery I found a 75cm long, 0.5cm diameter black corrugated tube coming out from the back under the wardrobe. It has a small hole at the end of it so it obviously needs to connect to something. I cannot see what/where and can only suspect I pulled it out from/off something as I got the battery out.
Any ideas gratefully received.
Thanks Jennie PS not great pictures

It’s the breather pipe for the battery. Should connect to small nipple on right hand side of battery near the top.
