The glazing unit as claimed in claim 1, wherein at least one of the at least two projecting parts extends continuously over a whole length of the at least one reinforcing element. 3. The glazing unit as claimed in claim 1, wherein the at least one reinforcing element comprises two lateral arms, each arm of the two lateral arms constituting a projecting part borne by the web part. 4. The glazing unit as claimed in claim 3, wherein the profile is a U-shaped profile with a concavity thereof facing away from the glazed element. 5. The glazing unit as claimed in claim 3, wherein at least one of the two lateral arms is folded over toward the other of the two lateral arms, at a right angle, at an end of the profile, and wherein bends in the profile are rounded. 6. The glazing unit as claimed in claim 3, wherein the two lateral arms are joined together along or at a small distance from free edges of the two lateral arms by a plate that is parallel or inclined to the web part with surface continuity with the web part. 7. The glazing unit as claimed in claim 6, wherein the two lateral arms are joined together by the plate over a whole length of the at least one reinforcing element. 8. The glazing unit as claimed in claim 6, wherein the two lateral arms are joined together by a plurality of plates that are spaced apart. 9. The glazing unit as claimed in claim 6, wherein the profile is formed by a strip of material folded over three times at a right angle. 10. The glazing unit as claimed in claim 3, wherein the profile includes a lateral arm that is folded over inwardly at least once at a free end of the lateral arm, the folded-over free end of the lateral arm contacting the web part at a point on the web part. 11. The glazing unit as claimed in claim 10, wherein the lateral arm is folded over on itself in a manner of a hairpin. 12. The glazing unit as claimed in claim 10, wherein the lateral arm is folded over once or twice at a right angle. 13.
