ABSTRACT:
This invention relates to a pipe coupling and, in particular, to a Victaulic-type coupling which generally comprise a pair of half shells, together forming a sleeve which can be placed around adjacent flanged or grooved ends of a pair of pipes which have been located in co-axial end to end relationship for joining. The pipe coupling of the invention comprises a pair of discrete, substantially identical half shells which are engageable with one another to form a coupling sleeve. The half shells each include a hook formation on one end thereof which is interengagable with the hook formation of the other half shell, partly to secure the half shells to one another.
