A locking mechanism for locking a movable member to a stationary member such as a movable door to a stationary door frame which comprises a member fixed to the door frame and having a projecting rim which cooperates with a U-shaped longitudinal section having a portion for connection to the movable door. The U-shaped longitudinal section receives the projecting rim. The U-shaped longitudinal section is adapted to receive one or more bolts which pass through the walls of the longitudinal section and are adapted to engage within slots or recesses in the projecting rim. At least one slidingly mounted rod is provided to carry the bolts which pass through the slots or recesses in the walls of the U-shaped section and engage the tongue shaped notches for locking the projecting rim with the U-shaped section. Additionally, two vertically adjustable bolts are connected with the sliding rod and these are adapted to engage the threshold and lintel of the door frame.
