Abstract
Abstract An easily manufactured, inexpensive, bicycle lock is provided with a U-shaped latch rod (3) with outside grooves (31) at its two ends, these ends being received into corresponding side holes of a tubular lock body (1) having a latitudinal hole. A protecting barrel (4) protrudes laterally of the lock body (1) to surround that end of the latch rod (3) inserted into one of the side holes to prevent easy breakage of the latch rod there. Covers (5) and (51) cover the lock body (1) (including the protruding barrel) and the latch rod (3) respectively. A lock core (2) engages one of the grooved ends of the latch rod (3) during use.
