An adjustable closure device comprising:

• a strap comprising at least a first end-region, and a central region;
• a connector attached to a terminus of the at least first strap end-region wherein the connector comprises a strap pivot bar around which the strap reverses direction;
• a chafe on the strap behind the connector, the chafe comprising:
• three parallel bars, a first outer bar, a central bar, and a second outer bar, wherein the first outer bar is proximate the first end-region of the strap, the second outer bar is proximate the central-region of the strap, and wherein a first strap pass-through gap is disposed between the central bar and the first outer bar, and a second strap pass-through gap is disposed between the central bar and second outer bar;
• and wherein the strap end-region comprises a strap path comprising segments arranged, directionally from the central region of the strap toward a strap terminus at the pivot bar of the connector, to (a) pass through the first chafe gap, (b) pass by the central bar of the chafe, (c) through the second chafe gap, (d) around the strap pivot bar of the connector, (e) return toward the chafe and to loop around the central bar of the chafe and terminate thereto, and wherein an adjustable length region of the strap comprises an adjustable span between the central bar of the chafe and the connector attached to it;
• and
• a handle connected to the chafe, wherein the handle is configured to allow a user to pull the chafe to which it is connected along the strap.
