Perhaps a reef knot might fit the bill.
But, Shirly, a bow is just a reefknot where the second overhand has the free end doubled over?
then, to convert to a double, the 2 loops are then crossed in another overhand hitch.- the double has to have the last hitch unpucked before a tug on any free end "should" release the bow.....but if the knotsmith ties a "granny," all bets are off. webbing and plastic "plug n' socket clips are the 21 st. century way.
