• a latch member, said latch member having a first end and a distal end;
• means for engagement of said first end of said latch member upon or immediately adjacent to said side edge of a door in an engaged position;
• said latch member in said engaged position, extending at an angle away from said door edge and toward said doorjamb for a distance positioning said distal end to continuously contact said doorjamb as said door moves from an open position toward a closed position surrounded by said doorjamb.
• a curved portion on said distal end of said latch member extending generally traverse to the direction of said latch member, said curved portion providing a contact surface for said distal end of said latch member with said doorjamb;
• said curved portion providing means to deflect said distal end over a door frame stop projecting above a surface of said doorjamb;
• a hook portion of said curved portion, said hook portion providing means to engage said latch member against a first side surface of said door frame, said first side surface being on a side opposite from the direction of said door moving toward said closed position;
• and
• said hook portion engaged against said first side surface providing a lock to maintain said door in a secured position by preventing rotation of said door toward said open position.
