The invention relates to a sealing connecting element, a sealing end piece and a seal. In practice different seals are known which are produced as three dimensional structures and then given to the customer. The production, wherein profile strips are ready-made by cutting and adhesion to form the three dimensional structures or wherein the three dimensional structure is obtained by means of corner injection molding, is very costly. In order to simplify the production of seals, it is provided in accordance with the invention that sealing connecting elements and/or sealing end pieces are to be produced as separate molded parts made of a thermoplastic elastomer and these molded parts to be connected, shortly before the installation of a seal, to sealing profile strips to form a complete seal.

1. A sealing connecting element for sealingly connecting at least one end of a first sealing profile strip to a second sealing profile strip, said connecting element comprising:a profile guide region having an insertion end for receiving the first sealing profile strip, said profile guide region being movable into position against an outer wall of said first sealing profile strip upon insertion of said first sealing profile strip into said insertion end; a profile guide region having an insertion end for receiving the second sealing profile strip, said profile guide region being movable into position against an outer wall of said second sealing profile strip upon insertion of said second sealing profile strip into said insertion end; a core portion arranged to guide one of said first or second sealing profile strips into one of said profile guide regions upon insertion of said one of said first or second sealing profile strips into said sealing connecting element, wherein said core portion and a wall of said one profile guide region define a space therebetween into which said one of said first or second sealing profile strips fits upon insertion of said one of said first or second sealing profile strips into said insertion end; a stop positioned to abut an end face of said one of said first or second sealing profile strips, wherein said stop, said core portion, and said wall of said one profile guide region form a channel for receiving said one of said first or second sealing profile strips; and wherein said sealing connecting element is configured such that upon insertion of the first and second profile strips into said sealing connecting element, said first and second profile strips extend in different longitudinal directions, said different directions being non-linear with respect to each other at the point of connection. 2. A seal comprising:(a) a sealing connecting element according to claim 1; (b) said first sealing profile strip of claim 1; and (c) a sealing end piece comprising a profile guide region being movable into position against an outer wall of said first sealing profile strip upon insertion of said profile strip into said profile guide region; said sealing end piece being formed as a molded part separately from said at least one profile strip and from a thermoplastic elastomer. 3. A seal comprising:(a) a sealing connecting element according to claim 1; (b) said first sealing profile strip of claim 1; and (c) a sealing end piece comprising (i) a profile guide region being movable into position against an outer wall of said first sealing profile strip upon insertion of said profile strip into said profile guide region, and (ii) an end wall for sealing a hollow chamber of said first sealing profile strip; said sealing end piece being formed as a molded part separately from said at least one profile strip and from a thermoplastic elastomer. 4. The seal according to claim 2 wherein said sealing profile strip, sealing connecting element, and sealing end piece are initially inserted in a loose manner and then adhered or welded together.5. The seal according to claim 3 wherein said sealing profile strip, sealing connecting element, and sealing end piece are initially inserted in a loose manner and then adhered or welded together.6. The seal according to claim 2 wherein said sealing profile strip comprises a base region and a sealing region.7. The seal according to claim 4 wherein said sealing profile strip comprises a base region and a sealing region.8. The seal according to claim 6 wherein said base region comprises an insert made of metal.9. The seal according to claim 6 wherein said sealing region comprises a hollow chamber region made of cellular rubber.10. The seal according to claim 8 wherein said sealing region comprises a hollow chamber region made of cellular rubber.11. The seal according to claim 2 wherein said at least one sealing profile strip is cut into lengths at an angle of substantially 90° with respect to its longitudinal direction prior to assembly with the sealing connecting element and the sealing end piece respectively.12. The seal according to claim 4 wherein said at least one sealing profile strip is cut into lengths at an angle of substantially 90° with respect to its longitudinal direction prior to assembly with the sealing connecting element and the sealing end piece respectively.13. The sealing connecting element of claim 1 wherein said space is filled by said one of said first or second sealing profile strips upon insertion of said one sealing profile strip therein.14. The sealing connecting element of claim 1 adapted for use in a motor vehicle.15. The seal of claim 2 adapted for use in a motor vehicle.16. The sealing connecting element of claim 1 further comprisinga second core portion arranged to guide the other one of said first or second sealing profile strips into the other of said profile guide regions upon insertion of said other sealing profile strip into said sealing connecting element, wherein said second core portion and a wall of said other profile guide region define a space therebetween into which said other sealing profile strip fits upon insertion of said other sealing profile strip into said insertion end; and a stop positioned to abut an end face of said other sealing profile strip, wherein said stop, said core portion, and said wall of said other profile guide region form a channel for receiving said other sealing profile strip.
