Abstract
A packer joint is provided for mounting on a vessel or pipeline entry valve which includes a stinger guide and an adjustable packer seal. A driving mechanism is mounted on the packer joint to which the stinger is connected for insertion through the packer joint into the vessel or pipe line. Improved clamping collets are mounted within the packer joint to retain the stinger in the desired position after insertion. A safety cap is provided for mounting on or around the packer joint and exposed end of the stinger after the stinger is inserted and the driving mechanism removed.
