The invention claimed is: 1. Insulating covering for a pressing jaw of a pair of pressing jaws for hydraulic or electric pressing tools for pressing fittings onto pipes or for the press connection of electric cables, comprising: a first portion defined by a pair of legs and a crosspiece extending between said legs, said pair of legs and said crosspiece of said first portion defining a substantially C-shaped cross-section; a second portion defined by a pair of legs and a cross-piece extending between said legs of said second portion, said pair of legs and said crosspiece of said second portion defining a substantially C-shaped cross-section; and an articulation portion between said first and second portions, said first and second portions and said articulation portion being formed of plastic. 2. Insulating covering as defined in claim 1, wherein said crosspiece of said first portion has a predetermined width and said crosspiece of said second portion has a predetermined width, and said articulation portion has a width which is widened relative to said crosspieces of said first and second portions. 3. Insulating covering as defined in claim 1, wherein the articulation portion is formed eccentrically in relation to a longitudinal extent of the insulating covering. 4. Insulating covering as defined in claim 1, wherein said widths of said crosspiece of said first portion and said crosspiece of said second portion are equal. 5. Insulating covering as defined in claim 1, wherein said first portion further includes a second crosspiece extending from each said leg which forms said first portion, and said second portion further includes a second crosspiece extending from each said leg which forms said second portion. 6. Insulating covering as defined in claim 1, wherein said articulation portion is U-shaped in cross-section. 7. Insulating covering as defined in claim 1, wherein said articulation portion enables said first and second portions to be able to move relative to each other. 8. Insulating covering as defined in claim 1, wherein said first portion has a length which is approximately three times a length of said second portion. 9. Insulating covering as defined in claim 1, wherein said first portion is generally convex along a longitudinal extent and said second portion is generally convex along a longitudinal extent. 10. Insulating covering as defined in claim 9, wherein said first portion curves at a different radius than the second portion. 11. Insulating covering as defined in claim 9, wherein said articulation portion is generally U-shaped along a longitudinal extent. 12. An assembly comprising: a pair of pressing jaws for hydraulic or electric pressing tools for pressing fittings onto pipes or for the press connection of electric cables, the two pressing jaws being disposed for rotation about an axis, each said pressing jaw including a peripheral edge terminated by first and second opposite ends such that a predetermined length is defined therebetween, said peripheral edge being parallel to said axis, a pressing jaw at said first end, and a drive surface at said second end; and an insulating covering extending along the entire predetermined length of each said peripheral edge, each said insulating covering including an articulation portion, a first portion attached to said respective pressing jaw and extending from said first end toward said second end and covering said first end of said peripheral edge and a predetermined portion of said peripheral edge proximate to said first end, and a second portion attached to said respective pressing jaw and extending from said second end toward said first end and covering said second end of said peripheral edge and a predetermined portion of said peripheral edge proximate to said second end, said articulation portion being formed between said first portion and said second portion and extending parallel to said axis and covering a predetermined portion of said peripheral edge. 13. An assembly as defined in claim 12, wherein a securing rib is provided on each pressing jaw for use in attaching said first and second portions to said respective pressing jaw, the respective securing rib projecting transversely to a longitudinal plane of the respective pressing jaw. 14. An assembly as defined in claim 12, wherein said insulating coverings can be attached and detached from said pressing jaws. 15. An assembly as defined in claim 12, wherein each said insulating covering is formed of plastic. 16. Insulating covering for a pressing jaw of a pair of pressing jaws for hydraulic or electric pressing tools for pressing fittings onto pipes or for the press connection of electric cables, comprising: a first portion defined by a pair of legs and a crosspiece extending between said legs, said first portion is generally convex along a longitudinal extent, said crosspiece of said first portion having a predetermined width; a second portion defined by a pair of legs and a crosspiece extending between said legs of said second portion, said second portion is generally convex along a longitudinal extent said crosspiece of said second portion having a predetermined width; and an articulation portion between said first and second portions, said articulation portion having a width which is widened relative to said crosspieces of said first and second portions. 17. Insulating covering as defined in claim 16, wherein said first and second portions and said articulation portion are formed of plastic. 18. An assembly comprising: a pair of pressing jaws for hydraulic or electric pressing tools for pressing fittings onto pipes or for the press connection of electric cables, the two pressing jaws being disposed for rotation about an axis, each said pressing jaw including a peripheral edge having a predetermined length; and an insulating covering extending along said peripheral edge and having a predetermined length, each said insulating covering including an articulation portion, a first portion attached to said respective pressing jaw, and a second portion attached to said respective pressing jaw, said articulation portion being formed between said first portion and said second portion, said first and second portion formed a convex shape with changing radii along its length. 19. An assembly as defined in claim 18, wherein a securing rib is provided on each pressing jaw for use in attaching said first and second portions to said respective pressing jaw, the respective securing rib projecting transversely to a longitudinal plane of the respective pressing jaw. 20. An assembly as defined in claim 18, wherein said insulating coverings can be attached and detached from said pressing jaws.
