They look like screw down terminals with a central 4mm socket. If its critical to avoid accidental disconnections, use crimp on fork terminals on whatever leads you make up. Alternatively most unshielded banana plugs should be fine.
The probe leads illustrated have half-length safety shields and aren't compatible with those terminals unless you trim the shields off and even then may be too short for reliable retention - check the socket depth with a matchstick and compare to the plug pin length before you butcher them. (Not that you want probe tipped leads on a bench PSU - croc clip ended ones are far more practical, or make dedicated leads with fork terminals for each project)
