snorkel keeper FTW, but since you asked....
The Aqualung ABS has an Octo holder designed just for it. Clips onto the metal hose connection. you can see it here
Aqualung Octopus ABS. Regulators Octopus, Scubastore.com, buy, offers, dive
I do not have any connection to Scuba store, they just have a good picture that shows some detail. Anyway you can buy one of these clips from any Aqualung dealer. It is aqualung part # 100924.
Or else you could use a snorkel keeper
