ABSTRACT:
A two-piece lock comprises a male connector; a locking mechanism provided on the male connector including a pair of connecting rods each having a rod portion and a slope portion, a pair of springs each putting on one of the rod portions, a tube member for receiving the springs and the rod portions on two opposite sides having a longitudinal center opening and a transverse center hole, a movable member having a head portion and a recessed body portion, and a pair of connecting members each pivotably connecting the rod portions and the recessed body portion which is pivotably secured to the tube member by inserting a fixing means through the transverse center hole and a predetermined position of the recessed body portion; and a female connector comprising a pair of holes on two opposite sides each receiving one of the slope portions in a locked position, and a recessed portion for receiving the head portion. As such, the locking mechanism is only seen by the head portion of the movable member for achieving a hidden safety mechanism. Further, the safety mechanism is enhanced by requiring to apply a predetermined force to slide the head portion of the movable member toward a predetermined direction prior to opening the lock.
