Abstract
A wireline releasable sealing connector is connected in a tubular pipe string together with a packer which is adapted to be set in the well casing. The connector is releasable and connectable without rotation of the pipestring. Tension is transmitted through the connector by a latching collet which is locked against release in response to relative longitudinal movement between an outer body and an inner sealing mandrel, unless, while the connector is in compression, a wireline tool is seated within the connector and engages a connector collet and thereby prevents locking of the latching collet.
