Zusammenfassung:	The present invention relates to a fastener for fastening a first element to a second element having an aperture and for sealing said aperture. The fastener comprises a first engageable means 12 for engaging with a first element (not shown) and a second engageable means 14 extendable through the aperture in the second element for engaging the edge portion means on each side of the second element. The second engageable means 14 includes a resilient skirt 16 having a resilient sealing ring 18 moulded to and engaging a peripheral lip 20 thereof, the lip 20 extending into the sealing ring 18. The sealing ring 18 is engageable with the edge portion means on one side of the second element for sealing the aperture in such a way that disengagement of the sealing ring 18 from the lip 20 is prevented.
