ABSTRACT OF THE DISCLOSURE A down-hole assembly is provided including particular structure for holding the assembly in place in a tubing hanger or the like. Camming wedges are associated with a cylindrical cage, the camming wedges being movable radially with respect to the cage to hold the cage in place in a tubing hanger. A tubular sleeve having camming portions thereon is concentric with the cage and effects radial move- ment of the camming wedges. A seal is also provided, and may include a structure that is radially movable from the cage into contact with the tubing hanger in response to axial movement of the sleeve. The sleeve may be locked in place to hold the camming wedges in holding engagement. Locking of the sleeve in place is effected by rotative movement of a locking nut. The sleeve may be released from its locked position either by reverse rotation of the locking nut or by release of an emergency retaining nut. A back pressure valve is mounted at the bottom of the cage, attached to a tubular mandrel extending concentrically with the sleeve and cage.
