The present invention relates generally to tools, tool kits and methods useful for performing surgery an SI joint. Each key has a horizontal surface sized to be received within a recessed portion on the refuse container and engage a lip on an upper periphery of the recessed portion. The pipe is thus restricted from swinging in the radial direction relatively against the joint and the reliability of the resistance force against pulling the pipe out of the connecting member by vehicle vibration, an increase of the internal pressure of the pipe and the like is improved.
