Dear Himadri,
The 55-250 does not accept any teleconverters.
The Canon Extenders 1.4x and 2x are accepted by most L series telephoto lenses from Canon. However if the resulting widest aperture is less than f/5.6 ie f/8 or so, they will not autofocus on most Bodies (except 1D series).
They work well with lenses like 70-200 f/4L IS, 70-200 f/2.8L IS, 300 f/4 L IS, 400 f/2.8L IS, 500mm f/4L IS, 600mm f/4L IS etc
