1. A holding device for supporting a workpiece, comprising main body means, lever means, pivot connection means pivotally interconnecting said lever means to said main body means, a first fixed abutment member carried by said main body means, a second abutment member carried by said lever means, said second abutment member being movable toward and away from said first abutment member upon pivotal rotation of said lever means, said second abutment member being movable by said lever means as to cooperate with said first abutment member to hold and support said workpiece, and disengageable latching means carried by said main body means and said lever means for maintaining said second abutment member in a selected position relative to said first abutment member as to thereby assure the continued holding and support of said workpiece. 2. A holding device according to claim 1 and further comprising anchor means for detachably securing said main body means to associated base-like support structure. 3. A holding device according to claim 2 wherein said anchor means comprises at least one pin-like member slidably receivable within said support structure. 4. A holding device according to claim 3 wherein said pin-like member is integrally formed with said main body means. 5. A holding device according to claim 2 wherein said anchor means comprises pin-like means extending generally downwardly from said main body means for slidable reception within said support structure. 6. A holding device according to claim 5 wherein said pin-like means are integrally formed with said main body means. 7. A holding device according to claim 1 wherein said latching means comprises a first latching portion rigidly fixedly carried by said main body means, and a second latching portion rigidly fixedly carried by said lever means, and wherein said second latching portion is disengageable from said first latching portion by forcibly deflecting said lever means and said second latching portion carried thereby away from said first latching portion carried by said main body means. 8. A holding device according to claim 7 wherein said first latching portion comprises at least one first tooth-like serration, wherein said second latching portion comprises at least one second tooth-like serration, and wherein said first and second tooth-like serrations serve to latch said lever means to said main body means against rotation in at least one direction about the axis of said pivot connection means. 9. A holding device according to claim 8 wherein each of said first and second tooth-like serrations are formed as to be generally aligned with radii of the axis of said pivot connection means. 10. A holding device according to claim 7 wherein said first latching portion comprises a plurality of first tooth-like portions, wherein said second latching portion comprises a plurality of second tooth-like portions, and wherein said plurality of first and second tooth-like portions are effective to cooperate with each other to latch said lever means to said main body means against rotation in at least one direction about the axis of said pivot connection means. 11. A holding device according to claim 10 wherein each of said plurality of first tooth-like portions and each of said plurality of second tooth-like portions are formed as to be generally aligned with radii of the axis of said pivot connection means. 12. A holding device according to claim 7 wherein said first latching portion comprises a plurality of first convolutions, wherein said second latching portion comprises a plurality of second convolutions, and wherein said plurality of first convolutions are effective to cooperate with said plurality of second convolutions in order to latch said lever means to said main body means against relative rotation of said lever means about said pivot connection means. 13. A holding device according to claim 12 wherein each of said plurality of first convolutions and each of said plurality of second convolutions are formed as to be generally aligned with radii of the axis of said pivot connection means. 14. A holding device according to claim 1 wherein said lever means comprises cavity means formed therein, wherein a portion of said main body means extends into said cavity means, wherein said pivot connection means pivotally maintains said portion of said main body means within said cavity means, and wherein said first abutment member extends through said cavity means. 15. A holding device according to claim 14 wherein said cavity means defines first and second lever portions spaced from each other, wherein said first and second lever portions are respectively situated at opposite sides of said portion of said main body means extending into said cavity means. 16. A holding device according to claim 7 wherein said lever means comprises an actuator plate effective to be manually engaged for latching and unlatching said latching means, said actuator plate being contoured as to form a trough-like portion effective for generally cradling a finger of a person operating said holding device, said trough-like portion serving to reduce the tendency of said person's finger sliding off of said actuator plate when forcibly deflecting said lever means to achieve disengagement between said first and second latching portions. 17. A holding device according to claim 1 wherein said main body means comprises a lower disposed mounting surface, and pin-like anchor means extending downwardly from said mounting surface, and wherein said mounting surface is substantially wider than the width of said pin-like anchor means measured in the same direction. 18. The combination of a sagger tray and a holding device for supporting a workpiece, said sagger tray comprising a mounting surface and a plurality of openings formed in said mounting surface, said holding device comprising main body means supported on said mounting surface and detachably fixed to at least certain of said openings, lever means, pivot connection means pivotally interconnecting said lever means to said main body means, a first fixed abutment member carried by said main body means, a second abutment member carried by said lever means, said second abutment member being movable toward and away from said first abutment member upon pivotal rotation of said lever means, said second abutment member being movable by said lever means as to cooperate with said first abutment member to hold and support said workpiece, and disengageable latching means carried by said main body means and said lever means for maintaining said second abutment member in a selected position relative to said first abutment member as to thereby assure the continued holding and support of said workpiece.
