A padlock is disclosed having an outer case preferably of hardened steel and having no shackle or bow which can be sawed or broken off. The case has an opening for insertion of a staple and has a slide bolt which extends through the opening to engage the staple. The slide bolt is secured by a locking means which includes a lock sleeve located within a cylindrical bore in the case, the sleeve being movable between a locked position and an unlocked position. The slide bolt is attached to the sleeve and extends through the opening when the sleeve is in the locked position. The lock sleeve has a retractable locking member projecting from a hole in the wall of the sleeve. The locking member is capable of fitting within an indentation in the interior bore wall when in the locked position to hold the sleeve in the locked position and capable of retracting into the hole to free the sleeve when in the unlocked position. A lock cylinder is fixedly mounted within the shell. The cylinder has an interior locking mechanism operatively connected to a camming means for forcing the locking member to project outwardly through the hole when the locking mechanism is locked and allowing the locking member to retract inwardly when the mechanism is unlocked.
