A security device for locking a double door mounted in a non-mullion passageway, the security device comprising:

• a latching element coupled to an interior surface of a first door of the double door, wherein:
• the latching element comprises a sliding bolt featuring a plurality of grooves around its circumference and an actuator operable for transitioning the sliding bolt between a locked state and an unlocked state, and
• the latching element is positioned proximate to an edge of the first door associated with a door knob;
• a receiving element coupled to an interior surface of a second door of the double door, wherein:
• the receiving element comprises an aperture featuring a plurality of grooves within its interior;
• and
• the receiving element is positioned proximate to an edge of the second door that is adjacent the edge of the first door associated with the door knob such that the aperture is positioned to receive the sliding bolt when the actuator is utilized to transition the sliding bolt to the locked state;
• a safety release accessible from a port in an exterior surface of the first door, the port providing access to the actuator such that the sliding bolt can be transitioned to an unlocked state;
• and
• wherein, when the sliding bolt is positioned in the locked state, the plurality of grooves around the circumference of the sliding bolt are operable to engage with the plurality of grooves within the interior of the aperture such that disengagement of the sliding bolt from the aperture is prevented when pressure is applied to the double door.
