Abstract
Abstract A connection between two components (2, 3) comprises an extension (5) from one of the components (2) which passes through a hole (6) in the other component (3). The extension (5) is formed from a plastics material having a memory ability and has a tubular shape. The edge of extension (5) is rolled over outwardly and backwardly towards the other component (3) and contacts it. A process for connecting the two components and a tool (9) for carrying out this process are also disclosed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
100 words
A connection between two components comprising an extension from one of the components which, for fixing purposes, passes through a hole in the other component, the extension being formed from a plastics material having a memory ability, wherein the extension has a tubular shape, projects beyond the other component, and an end portion of the extension which projects beyond the other component is rolled over outwardly and backwardly towards the other component and contacts said other component, the end portion of said extension being biased inwardly and contracting toward said extension due to the memory ability of the plastics material.
Claim 2
Dependent Claim
100 words
