1. Apparatus disposable within a subterranean wellbore, comprising:

  • a generally tubular first member having an axially extending bore internally formed thereon;

    a generally tubular second member having an outer side surface, the second tubular member being axially slidingly received within the bore;

    a first slip member, the first slip member grippingly engaging one of the first and second tubular members and preventing displacement of the one of the first and second tubular members relative to the other of the first and second tubular members in a first axial direction but permitting displacement of the one of the first and second tubular members relative to the other of the first and second tubular members in a second axial direction opposite to the first axial direction; and

    a second slip member axially spaced apart from the first slip member, the second slip member grippingly engaging the one of the first and second tubular members and restricting displacement of the one of the first and second tubular members relative to the other of the first and second tubular members in the first axial direction, but permitting displacement of the one of the first and second tubular members relative to the other of the first and second tubular members in the second axial direction.
