ABSTRACT OF THE DISCLOSURE This invention provides a pipe coupling which comprises a body having a threaded portion, a sealing element which provides a seal between the pipe and the body, a pipe-gripping collar and a threaded member which has threaded engagement with the threaded portion of the body. In use, it serves to contract the collar radially on to the pipe due to the coaction of wedge surfaces provided respectively on the collar and within the threaded member, the wedge surface within the threaded member being formed either on the threaded member itself or on an annular element which fits within a recess in the threaded member and is freely rotatable relative thereto.
