Well the tool you are thinking of is called a spanner wrench. However there are many sizes and options with jets, when someone says the jet body is loose then that usually means the backside of the jet body in the foam are of the spa and once you dig out the foam to expose the back of the jet body you can use a pipe wrench or channel lock pliers to tighten the locknut on the back which will tighten the jet body.
In most cases you can use tools you already have once you determine the size and shape you need. First take the skirting off and dig out any foam around the jets you think are loose and once that is done you just need to turn the locknut clockwise with a pipe wrench or channel locks.
