Abstract: The invention relates to a method for directly joining two end sections (3, 4) of corrugated pipes (1, 2), comprising the following steps: inserting the end sections (3, 4) of the corrugated pipes (1, 2) into a preferably inventive heat-shrinkable sleeve arrangement (8, 9); subjecting the heat-shrinkable sleeve arrangement (8, 9) to heat in the area of the end sections (3, 4) of the corrugated pipes (1, 2) so that the heat-shrinkable sleeve arrangement (8, 9) rests against the outside wall of the end sections (3, 4) of the corrugated pipes (1, 2), and; stress-free cooling the heat-shrinkable sleeve arrangement (8, 9) and the end sections (3, 4) of the corrugated pipes (1, 2) to a temperature at which the connection can be mechanically stressed. This enables end sections (3, 4) of corrugated pipes (1, 2) to be joined to one another easily and in a cost-effective manner.

Abstract: The invention relates to a fixing element for fixing a component to a support part. The element comprises a retaining part (1) for the component to be fixed and a hollow anchor foot (2), which is used to anchor the fixing element in a continuous bore of the support part. Two spring arm pairs (5, 6), which widen towards the retaining part (1), run from the lower edge in opposing openings (4) in the wall of the anchor foot (2), one short and one long spring arm (5 and 6) respectively lying adjacent to one another in one of the openings (4) and being offset in relation to the short and long spring arm (5 and 6) in the other opening (4). As both spring arm pairs (5, 6) are graduated towards the retaining part (1), starting from a respective outer edge (11, 12) that lies at the greatest radial distance from the central axis (M) of the fixing element, front faces (7, 8) and step faces (9, 10) are created on different horizontal planes. The faces can rest on the underside of a support part.
