A joint restraint includes a split ring terminating in radially outwardly extending flanges. A shell includes a cylindrical sleeve, an annular flange at one end and arms projecting generally tangentially for securement behind lugs on a standard bell end of a fitting. With the split ring disposed within the shell and flanges projecting through a radial opening through the shell, a pipe end may be inserted through the joint restraint into the bell. By compressing the split ring about the pipe end by drawing the flanges toward one another and bolting them in place, relative axial movement of the pipe end and fitting is precluded by engagement of the shell flange and split ring.
