- 12. A lock as set forth in claim 11 wherein said lock housing also includes a non-round portion.
- 13. A lock as set forth in claim 12 wherein said non-round portion comprises at least one flat on the side of said lock housing.
- 14. A lock as set forth in claim 10 including a flag mounted on said lock bolt for rotation therewith.
- 15. A lock as set forth in claim 14 including a lock nut mounted on said lock bolt on the opposite side of said flag from said lock housing.
- 16. A lock as set forth in claim 15 wherein said lock bolt includes a head, and a key-receiving face on said head.
- 17. A lock as set forth in claim 16 wherein said key-receiving face is located within said lock housing.
- 18. A lock as set forth in claim 17 wherein said head includes a curvilinear groove in said key-receiving face.
- 19. A lock as set forth in claim 18 wherein said lock housing includes a threaded portion, and jam nut wherein said is mounted on said threaded portion.
- 20. A lock as set forth in claim 19 wherein said lock housing also includes a non-round portion.
- 21. A lock as set forth in claim 20 wherein said non-round portion comprises at least one flat on the side of said lock housing.
- 22. A lock as set forth in claim 1 wherein said lock bolt includes a head, and a key-receiving face on said head in said lock housing, a threaded portion on said lock housing, and jam nut wherein said is mounted on said threaded portion.
- 23. A lock as set forth in claim 22 wherein said lock housing also includes a non-round portion.
- 24. A lock as set forth in claim 23 wherein said non-round portion comprises at least one flat on the side of said lock housing.
- 25. A lock as set forth in claim 24 wherein said lock housing includes a lip on the end thereof which is larger than said undulating end.
- 26. A lock as set forth in claim 22 wherein said lock housing includes a lip on the end thereof which is larger than said undulating end.
- 27. A lock as set forth in claim 1 including means for limiting rotational movement of said undulating face of said torque plate relative to said undulating end of said lock housing.
- 28. A lock as set forth in claim 27 wherein said means for limiting rotational movement comprise at least one first shoulder on said lock housing, and at least one second shoulder on said torque plate.
- 29. A lock as set forth in claim 27 including a key therefor wherein said means for limiting rotational movement comprise at least one first shoulder on said key, and at least one second shoulder on said housing.
- 30. A lock as set forth in claim 1 including a key therefor, a flag mounted on said lock bolt for rotation therewith and for movement between a first locking position and a second unlocking position, and key-retaining means for permitting separation of said key and said housing when said flag is in said first position and retaining said key relative to said housing when said flag is in said second position.
- 31. A lock and key therefor as set forth in claim 30 wherein said key-retaining means comprise a ridge on said key, and a lip on said housing.
- 32. A lock and key therefor as set forth in claim 30 wherein said key-retaining means comprise a first wing on said key, and a second wing on said housing.
- 33. A lock and key therefor as set forth in claim 31 wherein said second wing comprises a bracket mounted relative to said housing.
- 34. A lock and key therefor as set forth in claim 30 including means for limiting rotational movement of said undulating face of said torque plate relative to said undulating end of said lock housing.
- 35. A lock and key therefor as set forth in claim 34 wherein said means for limiting rotational movement comprises at least one first shoulder on said lock housing, and at least one second shoulder on said torque plate.
- 36. A lock and key therefor as set forth in claim 34 wherein said means for limiting rotational movement include at least one first shoulder on said key, and at least one second shoulder on said housing.
