Abstract
A bowl and slips assembly for supporting tubing in a well includes a plurality of gripping inserts supported on slip bodies by means of a cantilever connection with the inserts hang-supported from the top surfaces of the bodies so the bodies are in compression when supporting tubing in the well. In comparing adjacent slip bodies, one includes a shoulder formed in the top surface thereof so adjacent inserts are supported in vertically spaced positions. A safety ledge integrally formed with each body prevents broken inserts from falling into the well.
