A well tubing hanger for suspending a pressure bomb and/or temperature recording device, or other equipment in the tubing from a tubing no-go nipple, through a test period. It is a bomb hanger such that when the suspended equipment is being used for test surveys, the wire line used to run the tools is not left in the well. This results in considerable savings; particularly when a plurality of wells in a field are being surveyed. Tubing hanger locking lugs are shifted radially outwardly into a nipple recess by a longitudinal, movable camming and lug-locking tubular sleeve extension from the tool fishing neck, with the sleeve lockable by a ball recess lock interference fit. A resiliently displaceable plunger structure permits a recess relief unlock for the balls, from the ball recess lock interference fit and thereby permits unlock release movement of said tubular sleeve, with the tool fishing neck, for unlocking the locking lugs from the extended state.
