A Universal Serial Bus (USB) flash drive includes a slim USB device having an end used to couple the USB flash drive to a host and an opposite end, and a swivel “strap shaped” metal cap having a circle cut out disposed on both cap legs. The snap coupling circle attachment allows the swivel cap to rotate substantially into a first and a second locking position and to rotate substantially 360 degrees about the z-axis of the USB device. The metal cap is generally in a locked position when the snap slot is aligned atop the snap lock tabs such that the protrusion snap ring is descended downward until the positioned flush against the snap lock groove. When unlocked the protrusion snap ring is raised up and rested upon the two snap lock tabs.
