ABSTRACT:
A latching device for locking and removal of a flow control device from a mandrel receiver comprises a cylindrical stem, a locking sleeve slidably mounted upon the stem, an annular locking ring mounted for a limited axial movement along the lower portion of the locking sleeve and a compression spring. The annular locking ring has upper and lower bevel surfaces which are complementary to bevel surfaces of a mandrel receiver. An improved retrieval device is disclosed for retrieval of a valve which is locked within the mandrel receiver, the device comprising a cylindrical body having a central opening and an internal wall with a recess and a retrieval tool provided with a compressible C-shaped ring for locking engagement with the recess formed in the cylindrical body, thereby allowing retrieval of the cylindrical body, along with the well tool which is securedly attached to the retrieval device.
