That's what I thought from looking at ATT's images on their site but I've found some posted by owners and the strap is loose at the ends so you just pull it tight to hold handle. head etc in place the ends of the straps are then tucked underneath to hide them if so desired.
The following image hopefully shows that more clearly than my description.
Going to have a go at that configuration next to see how well it works, would have had it done today but I've been waiting downstairs for a parcel delivery that so far hasn't arrived!!
