This patent describes a tubing anchor assembly for supporting tubing in a well. The tubing anchor assembly is characterized by tubing support means having an internal bore and a tapered slip bowl in the bore; retainer means threadably and radially deployed in the tubing support means in spaced relationship and shaped ends on the retainer means, the shaped ends projecting into the slip bowl; slip means disposed in the slip bowl and dove tail slot means provided in the slip means, the dove tail slot means engaging the shaped ends on the retainer means, respectively. The improvement described here in combination therewith comprises bevelled top faces provided on the slip means, whereby the slip means are suspended on the shaped ends in a first selected orientation and are released from the shaped ends and dropped into supporting contact with the tubing responsive to threadable rotation of the retainer means in the tubing support means, in a second selected orientation. The shaped ends are extended into engagement with the bevelled top faces responsive to further threadable rotation of the retainer means.
