A closure is made up of a strap (110, 210, 310, 410, 510, 610) and a holder (130, 230, 330, 430, 530, 630) that engages with the strap while it tightens and loosens, and a retainer (170, 270, 370, 470, 570, 670), which retains the holder in one of the two positions relative to the strap. For items opening lengthwise (e.g., sneakers), the closure includes a lace (795). To unlock the closure, the user moves the holder to the unlocked position. To lock the closure, the user pulls the strap, which automatically moves the closure back to the locked position. The strap has two sets of teeth (112, 114, 212, 214, 312, 314, 412, 414, 512, 514, 612, 614). One set (112, 212, 312, 412, 512, 612), the switching teeth, automatically moves the holder from the unlocked position to the locked position.
