US Army Strap 173cm long and 5cm wide

Strap 173cm long and 5cm wide
Hello, I just found this strap in a flea market. Not a militaria seller, but it was surrounded by a Jungle First Aid Pouch 1945 and a Survival Ax LC-14-B holster.
I was told, this is a belt, but I doubt it.
It is 1,73m long and 5cm wide (two inches), olive in color. In the buckle, there is the letters IHB and “PRESS TO LOCK” in the other side, also, in the web strap, very subtle, IHB and US with black ink.
It was made very sturdy, like it was for hold things in a vehicle, to hold a jerrycan in a Jeep,for example.
Can you identify it? Thanks in advance.

utility strap for attatching things like ammo cans or gas cans to alice pack frames or the old pack boards. You see these used to tie down gas cans on vehicles to thier mounts too..
