Abstract

There is disclosed a pipe coupling 1,which may be a straight coupling, a bend or a T-piece, and which has at least one internal-thread 3 for connecting the coupling to a pipe end of a pipeline. A polygonal head 4 is formed externally on the coupling in the neighbourhood of the internal thread 3, for engagement by a pipe wrench to connect, or disconnect the coupling with respect to the pipe end. The pipe coupling is formed in a mould such that two corners 7 of an octagonal head 4 are arranged along the mould parting plane, to permit ready removal of the coupling.
