A centralizer for mounting onto a downhole tubular incudes a cylindrical body. The body has: a plurality of blades forming a periphery thereof, a first portion with an inner surface, and a second portion having a groove formed in an inner surface thereof for receiving a stop collar. The stop collar includes: a compressible slip ring having teeth formed in an inner surface thereof and a pair of tapered outer surfaces, and a pair of cam rings, each cam ring having a tapered inner surface. An outer diameter of each cam ring is greater than a diameter of the inner surface of the first portion and less than a diameter of the groove. An assembly tool is operable to drive the tapered surfaces together, thereby compressing the slip ring such that the teeth engage a periphery of the downhole tubular.
