A push button door locking mechanism including a push button mounted on a push button carrier housed within an inside spindle of a door lock assembly, a main retractor co-rotatingly attached to the spindle, and an inner cam aligned axially with the push button carrier. The inner cam has a flange portion extending substantially perpendicularly from a driver bar portion of the inner cam. The locking mechanism also includes a locking catch assembly having a first end and a second end. The first end includes a head portion formed to matingly engage the push button carrier. The second end is coupled to a locking wing. The locking catch assembly has a locked position wherein the locking wing matingly engages the flange preventing rotation of the flange with respect to the main retractor and an unlocked position allowing rotation of the flange with respect to the main retractor.

The cover plate of claim 4, wherein said drive bolt drives said cam plate toward said front surface after said latch bar moves outward. 6. The cover plate of claim 4, wherein said drive bolt drives said cam plate away from said front surface before said latch bar moves inward. 7. The cover plate of claim 4, wherein movement of said drive bolt in a first direction results in movement of said cam plate toward said front surface and movement of said latch bar outward from said side surface. 8. The cover plate of claim 4, wherein movement of said drive bolt in a first direction results in movement of said cam plate away from said front surface and movement of said latch bar inward toward said side surface. 9. A protective cover plate for a stortz connection of a piping system, said cover plate comprising a front plate, a stortz fitting extending rearward from said front plate, and a sliding plate locking mechanism being disposed rearward of said front plate and being adapted to engage a concealed portion of said piping system when said cover plate is assembled to said piping system, said sliding plate locking mechanism comprising an indicator assembly that provides visual confirmation of an operational characteristic of said sliding plate locking mechanism. 10. The cover plate of claim 9, wherein said stortz fitting and said front plate are formed separately from each other and said stortz fitting forms a portion of an adapter ring that is connected to said front plate. 11. A protective cover plate for a stortz connection of a piping system, said cover plate comprising a front plate, a stortz fitting extending rearward from said front plate, and a sliding plate locking mechanism being disposed rearward of said front plate and being adapted to engage a concealed portion of said piping system when said cover plate is assembled to said piping system, said sliding plate locking mechanism comprising a single exposed moving component when said cover plate is assembled to said piping system. 12. The cover plate of claim 11, wherein said stortz fitting and said front plate are formed separately from each other and said stortz fitting forms a portion of an adapter ring that is connected to said front plate. 13. A method of installing a cover plate to a piping system having a stortz fitting, said method comprising inserting said cover plate into said stortz fitting, rotating said cover plate to secure said cover plate to said stortz fitting, turning a cam plate, translating a latch bar, indicating a movement of said latch bar, and loading an actuator assembly with a tamper-resistant torsion load, said translating movement of said latch bar being indicated by rotational movement of an indicator drum. 14. The method of claim 13, wherein said cam plate is turned only while said cam plate is engaged with a torque limiting assembly.
