This patent describes an apparatus engageable with the wall of a well bore and attached to a tubing string in the well bore to anchor the tubing string against axial movement, in which at least one separate fluid pipe is attached to the exterior of the tubing string. The apparatus consists of: a tubular body connected to the tubing string and having an axial passage of area equal to the tubing string bore communicating with the bore of the tubular body; anchoring slip means concentrically encircling the tubular body; expander means concentrically encircling the tubular body and adjacent to the anchoring slip means and relatively axially shiftable for expanding the anchoring slip means; means responsive to rotation of the tubular body for shifting the expander means axially relative to the tubular body to expand the slip means; the tubular body having an axially extending groove in its exterior surface extending axially through the encircling expander means and slip means, a second pipe disposed in the full length of the groove; and means for attaching the second pipe to the separate fluid pipe to conduct fluids to a well bore location below the tubular body without reduction in fluid passage area of the tubing string.
