A heater used on a body having a substantially cylindrical outer surface has a heatable generally cylindrical sleeve fittable over the body and having one end formed with a screwthread and a ring threadable into the screwthread locks the sleeve on the body. More particularly the ring is also formed with a screwthread complementary to the body screwthread and both screwthreads are tapered. This ring is split along its full length so that when the ring is screwed into the body it is compressed radially of a central axis of the body.
