The disclosed invention relates to a padlock comprising a U-shaped-shackle. The invention discloses a sleeve that fits tightly, mostly covering or surrounding a portion of the straight portion of the shackle-toe and wherein the sleeve also fits loosely and mostly covering or surrounding a small portion of the U-shaped-shackle-head nearest the shackle-toe. The sleeve being designed to deter a jawed manual bolt-cutting tool from cutting apart the shackle-toe of a padlock that comprises a U-shaped shackle. The sleeve also being designed large enough to be prevented from being pulled through the hole, staple, or link the padlock shackle is secured therein, therefore, mandating the shackle-toe remains in the hole, staple, or link the shackle-toe is secured therein. After cutting the shackle-heel or the shackle-head apart and wherein a portion of the U-shaped shackle-head remains attached to the shackle-toe, the disclosed invention sleeve will remain secured in place on the shackle-toe as any curved portion of the shackle-head will not allow the sleeve to slide off of its position on the shackle-toe, therefore, the padlock remains locked and secured in place.

An anti-theft apparatus that attaches to a shift lever and a foot rest of a motorcycle includes a shackle that is sized and shaped to extend from the foot rest to the shift lever. The shackle has an open end, a second end opposite of the open end, and two elongate arms that extend between the second end and the open end. A locking mechanism engages with the open end of the shackle to lock the shackle into place around the foot rest and the shift lever. A lock plate is coupled to one of the elongate arms of the shackle. A cross bar plate removably attaches to the open end of the shackle and is configured for being positioned between the locking mechanism and the shift lever when the apparatus is attached to the motorcycle. When the apparatus is attached to the motorcycle, the motorcycle shift lever cannot be operated, thereby deterring theft of the motorcycle.

A hoop lock including a shackle and a crossbar, with the shackle having a pair of legs extending from a body portion, and each of the legs having a foot including a tip with a non-circular cross-section. The cross-bar includes a housing having a pair of foot-receiving openings and a pair of tip-receiving openings substantially aligned with foot-receiving openings. The tip-receiving openings are configured to matingly engage the tips such that the tips are rotationally coupled to the housing.
