A latching assembly having a retractable latch bolt and a slide bar which retracts the latch bolt by moving either forwardly or rearwardly from an intermediate position. The latching assembly has a rotatably mounted locking rod that rotates 90 DEG between a locking and an unlocking position. The assembly is arranged with a "panic release" system, in that with the locking rod in its locked position, it is possible to push an "inside" button or cylinder forwardly so as to move the locking rod to at least a partially released position to permit the latch bolt to be retracted. Thus, the latch bolt can be retracted from the inside location whether the locking rod is in its locking or unlocking position, but cannot be retracted from the outside location when the locking rod is set in its locked position.
