Abstract
A thrust restrainer for a joint in a pipeline between a plain end of a synthetic plastic pipe and a fitting comprises a pair of semicylindrical moulded half sleeves bolted together through diametrically extending flange portions, the half sleeves having at one end an internal profile complementary to that of the fitting, and at its other end a semicylindrical internal profile matching the external surface of the pipe, the semicylindrical profile including a plurality of parallel serrations which deform the material of the pipe into engagement with the serrations on bolting together of the half sleeves.
