发明名称 Pipe joint
摘要 There is disclosed a pipe joint comprising a first pipe having an end portion engaged as a snug fit in a concentric end portion of a second pipe. The pipes have, at positions spaced from their adjacent ends, external annular ribs with corresponding internal annular grooves, an annular seal being accommodated in the annular groove of the outer pipe between the outer pipe and the inner pipe. A clamping ring which spans the annular ribs of the two pipes comprises two arcuate parts connected end to end by a hinge and having at their ends remote from the hinge outwardly turned edge formations which are received in a wedge-shaped channel member and engage relatively inclined opposing side walls of the channel member. The clamping ring can simply be closed around the pipe joint by relative pivoting of the two arcuate parts and can be retained by sliding the wedging member, in a direction parallel with the axis of the pipe joint, over the edge formations at the ends of the arcuate parts remote from the hinge.
