Claim Text:
1. An apparatus for adapting an elevator for use with a tubular, comprising: one or more axial extensions configured to engage one or more slip bodies of the elevator, the one or more axial extensions comprising a radial contact surface configured to slide along the tubular and an axial engagement surface configured to bear on an upset of the tubular, wherein the axial engagement surface and the upset are substantially perpendicular to a central longitudinal axis through the tubular, wherein the axial engagement surface bearing on the upset of the tubular causes an axial force to be transmitted through the one or more axial extensions, which causes the slip bodies to be displaced radially inward, and wherein the one or more axial extensions are flexible such that the radial contact surface is radially displaceable with respect to the tubular.
