In this case the daftest thing is making the lead captive to the tester. If it just plugged in, then the remedy to the problem would just be send a new lead to anyone affected.
I doubt I have a tester on it's original set of leads, they get damaged, you replace them. Except with these you can't.
my T140 is now on its 3rd lead. not at easy swap, the PCB has to be removed and the old lead desoldered and the new one soldered in. probe end its cut then crimped & heatshrinked
