What is that loop you hold on to when you ride a bus/subway?

What is that loop you hold on to when you ride a bus/subway?

Is it called a loop of some sort? Or handle? In the picture below, an invisible... ?

Solution 1:

Bus-strap

"Here is a bus driver grabbing onto typical straps"

Grab/ Grab Handle

"City Bus Plastic Grab Handle"

Solution 2:

The standing passenger has his own page.

hanging strap: a strap suspended from the ceiling with a handle provided for standing passengers to hold on to

handrails: running horizontally along the ceiling

stanchions: vertical poles

grab rails: smaller hand rails attached to seats, doors and doorways

And whether it is a train, subway car, bus, or car I would probably just call them oh-shit handles.
