Abstract: A training device for training the techniques of forcible entry through a locked door includes a door having an inner vertical edge, the door being hingedly mounted within a door frame for swinging movement between closed and open positions, the door frame including a hollow vertical jamb having a vertical surface adjacent the inner vertical edge of the door and an opening in the vertical surface communicating with the hollow. A pin projects from the door and is received within the opening in the jamb. When the door is in the closed position the pin is clamped by a pair of vertically opening and closing hinged jaws, the jaws being operable within the hollow between open and closed positions and being biased into the closed position by compression springs.
