Abstract
A stabbing box structure that acts as a safety slip. It has a split construction with a clamp to hold it onto the flange of an end connector of a section of tubing which is being supported at the well head by slips. There is a tapered guide interior construction in the box which is for guiding the end connector of another section of tubing that is stabbed into the box. The tube being stabbed is guided into abutting alignment with the end connector that has the stabbing box clamped thereon. The stabbing box has an outside diameter that is greater than the opening at the well head. Consequently, if the slips holding the tubing string already in the well should let go, the stabbing box will prevent the tubing string from falling into the well.
