The low 100 mV / division vertical sensitivity, a very low operating frequency and the shortness of the lead are the reasons why Tek did not shield this connection.
Anything that completes the circuit to the center pin is sufficient. I suggest soldering or crimping a pin on the end of the lead, followed by several layers of gradually larger shrink tubing to provide a handle and stop the lead from falling inside the 7CT1N when retracted. A rigid plastic probe handle cut short and epoxy (JB Weld?) might also work. At a maximum voltage of 0.8 volts, there should be no safety issues.

Could this be used? It is with me more than 40 years, probably it was
manufactured by Pomona.
