Bogen used to sell wide straps with a special threaded screw which fit the threaded hole in the spider of Bogen (Manfrotto) tripods, like this strap on a Bogen 3221 tripod (predecessor to Manfrotto 055)...
...and a loop at the other end, that could slip over one/all the tripod legs (to hold them closed). I still own a Bogen 3236 tripod with Bogen strap like the one pictured, although I sold the 3221 with its strap.
Now I use an Optech Super Classic controlled stretch strap with 'binocular ends' with my Gitzo 2530, to form a suitably sized loop at the ballhead/column (shown) and another loop at the other end which is sized to fit one of the tripod legs...
