you can get the clips from lwsco on e bay or a welding/compressor& air tool shop,they are calibrated to suit the o/d of the hose.I have a large roll of this pipe u can have some @ cost price ±p&p,or collect,i'm 18m from brecon ,nr hay-on-wye.Any suggestions on where to purchase the hose & clips from.
Is it a specific welding item etc.
I have an air line which looks the same, clear plastic. No idea on the bore though.
