<p>A pipe coupling (2) comprises:- a) a first coupling section (4); and, b) a second coupling section (16), whereby, in use, the first and second coupling sections (4, 16) are co- joined and placed between opposed ends (8, 10) of a pipe to be coupled whereupon the first and second coupling sections (4, 16) are moved axially with respect one to the other to engage with respective ones of the opposed ends (8,10) of the pipe, wherein the coupling sections (4, 16) each comprise a locking portion (18, 26) to facilitate, in use, mutual engagement between the respective locking portions (18, 26) and locking of the pipe coupling in place between the opposed ends (8, 10) of the pipe as aforesaid, characterised in that the locking portion of the first coupling section is provided by a series of annular ribs (18) extending part way about a peripheral external wall of the first coupling section and the locking portion of the second coupling section is provided by a series of annular grooves (26) extending part way about an internal peripheral wall of the second coupling section for receiving, in use, the annular ribs (18) of the first coupling section.</p> |
