The invention relates to a process for bringing about a permanent connection between at least two components, one of which components is obtained by moulding of a thermoplastic elastomeric material, characterized in that the component is subjected to a treatment comprising the following steps:a. stretching of the component of thermoplastic elastomeric materialb. relaxation of the component subjected to step (a) at ambient temperaturec. placement of the component obtained sub (b) at the location of the desired connection in the objectd. exposure to an increased temperature of at most about 20° C. below the melting point of the thermoplastic elastomer.Application of the process of the invention, in particular during step (d), produces a shrunk connection which provides a permanent seal under tension.The invention may be applied for many types of connections and seals, for example body plugs, shrink-on sleeving, sealing rings, etc. Especially suitable, particularly in automotive applications, are copolyether esters.

1. A process for fashioning a permanent connection between at least 2 components, at least one of said components being a thermoplastic sealing or connecting member obtained by molding a thermoplastic elastomeric material, at least one other component being a non-sealing member, said permanent connection being located at a desired location of said non-sealing member, comprising:a. stretching said sealing or connecting member; b. relaxing said stretched member from step (a) at ambient temperature; c. placing said member from step (b) at the desired location on said non-sealing member; and d. exposing said members from step (c) to an increased temperature of at most about 20° C. below the melting temperature of the thermoplastic elastomeric material. 2. A process according to claim 1, wherein the thermoplastic elastomeric material is a copolyether ester.3. A process according to claim 1, wherein the thermoplastic elastomeric material comprises a block copolymer comprising hard blocks, wherein said hard blocks comprise polyurethane, polyester or polyamide.4. A process according to claim 1, wherein the thermoplastic sealing or connecting member is a body plug, gasket ring, sealing ring, or shrink-on sleeving.5. A process for fashioning a permanent connection between at least 2 components with at least one thermoplastic sealing or connecting component obtained by molding the component from a thermoplastic elastomeric material, stretching the component, and relaxing the component at ambient temperature, and at least one non-sealing member, comprising:a. placing said thermoplastic sealing or connecting component at the location of the desired connection on said non-sealing member, and b. exposing said thermoplastic sealing or connecting component to an increased temperature of at most about 20° C. below the melting point of the thermoplastic elastomeric material. 6. A process for fashioning a permanent connection between at least 2 components, with at least one thermoplastic sealing or connecting component according to claim 5, wherein the thermoplastic elastomeric material is a copolyetherester.7. A process according to claim 5, wherein the thermoplastic elastomeric material comprises a block copolymer comprising hard blocks, wherein said hard blocks comprise polyurethane, polyester or polyamide.8. A process according to claim 5, wherein the thermoplastic sealing or connecting member is a body plug, gasket ring, sealing ring, or shrink-on sleeving.
