The lock comprises an elongate lock member having a flat end section with a central opening at one end of the lock member and a shank portion at the opposite end thereof. The flat end section is insertable between an edge of the door and the door frame. A hook element is connected to this end section and is located adjacent the central opening so as to project into the hole in the door frame during use of the lock. An integral tongue element has one end thereof connected to the shank portion and has a door engaging portion biased by spring action to move from a first position where the door can be opened or closed to a second position where the door is blocked and prevented from opening. Preferably the lock is made from spring steel.
