A back plate serving as a slide bolt frame is designed to be fastened to a door such as a garage door to position a latch bolt slidably mounted on pivot tabs of the back plate. A cover plate has complementary pivot tabs which engage the latch bolt and pivotally mount the cover plate on the back plate. Both plates are also provided with a pair of locking tabs positioned so that one tab of each pair lies adjacent one tab of the other pair for engagement by the shackle of a padlock. In this way, the cover plate is held in an overlying position protecting the padlock. A transverse projection on the latch bolt has a slot engageable with tabs of each pair thereby to lock the latch bolt in either extended or withdrawn position.
