Abstract
An apparatus for securing to a tubular includes a tubular base configured to be disposed around the tubular, the base defining a longitudinal central axis therethrough and including axial ends. The apparatus includes fingers extending from at least one of the axial ends of the base and substantially parallel to the longitudinal central axis. The fingers are separated circumferentially apart by slots, at least one of which does not extend across the base. The apparatus includes a sleeve configured to be disposed around the tubular and slid straight axially over the fingers, such that an elasticity of the sleeve provides a radially-inward gripping force on the fingers. The gripping force prevents the base, the plurality of fingers, and the sleeve from rotating relative to the tubular and from moving axially relative to the tubular. The sleeve may abut a stop wall of the base when slid onto the fingers.
