Abstract
A pipe coupling includes a body, a center ring at each end of the body, and an end ring coupled to the center ring by means of an annular rim located at an axially-inner end of the end ring. The annular rim extends radially outwards to form an annular hollow portion that fits over and is coupled to the center ring. A retaining device is positioned to snugly press against the annular rim so as to press the end ring and the annular rim against the center ring, thereby maintaining the end ring and the annular rim in a position which is concentric with the center ring and the body of the pipe coupling.
Claims4
A pipe coupling comprising:
- a body, a center ring at each end of said body, and an end ring coupled to the center ring by means of an annular rim located at an axially-inner end of said end ring, said annular rim extending radially outwards to form an annular hollow portion that fits over and is coupled to said center ring;
- and
- a retaining device positioned to snugly press against said annular rim so as to press said end ring and said annular rim against said center ring, thereby maintaining said end ring and said annular rim in a position which is concentric with said center ring and said body of said pipe coupling;
- wherein said retaining device is positioned to press against an inner surface of said annular rim;
- wherein said retaining device comprises a resilient wire shaped to fit in said annular hollow portion and press against said annular rim;
- and
- wherein said resilient wire extends through said annular hollow portion so that two opposite ends of said resilient wire meet each other 180° from a top portion of said retaining device.
