I got crocodile clips with my multimeter, but no cable with them. The tips of the probes I have, do not fit into the plug on the crocodile clips.

Crocodile Clip

How do I connect them to my multimeter? What kind of cable do I need?

I assume this is some kind of standard connector, I searched around but did not find anything useful. Seems I just lack the exact name of this kind of connector.

Update: The multimeter is a Testo 760-3 with the default probes. They have a small ~2mm conic tip.

Here a picture of the probe tip:

  • \$\begingroup\$ Can you put the model of your multimeter (or at least the brand). The female port behind the crocodile clips seems to be designed to accept something. \$\endgroup\$ – Dat Nov 3 '16 at 11:56

    \$\begingroup\$ Either get 2mm "banana plug" connectors or remove the 2mm->4mm adapter and get regular 4mm "banana plug" connectors. \$\endgroup\$ – Janka Nov 3 '16 at 11:56

    \$\begingroup\$ Have you tried sticking the test prod needle point into the round ferrule at the end opposite to the jaws? Does the point fit into it and stay firmly attached? \$\endgroup\$ – FiddyOhm Nov 3 '16 at 11:56

    \$\begingroup\$ Does your multimeter have 4mm sockets? If yes, get two cables with a banana plug, and de-solder these non-matching adapters from the clips. The 4mm banana plugs should fit into the new opening perfectly. \$\endgroup\$ – Janka Nov 3 '16 at 16:27

My guess would be that the clip is intended to fit over the probe but it is being stopped from doing so by the plastic sheidling on the probe tip.

On some probes the plastic shielding on the tip is removable. It may be that you need to remove it to use the croc clip. It may also be that the vendor screwed up and shippped clips that were not compatible with the test leads.

The probes for my meter look something like that - the plastic over the metal probe just pulls off - then the probe tip should fit into the clip.

The instructions for those clips state

Simply put the measuring cables into the crocodile clip.


I notice that there is a considerable amount of insulation missing from the clips in your photo as compared to the published configuration.

If the leads you show are the standard ones then your ones have an additional sleeve on the end - it could be that someone has previously attached the leads to the clips and broken them when trying to remove them.

You can strip a piece of wire at one end and clamp it to the crocodile clip using a bullet crimper tool. The other end probably a banana jack assume that your multimeter accepts it.

  • \$\begingroup\$ It is extremely unlikely that this is the intended usage of that croc clip. The slightly unusual blunt end suggests some intended connectivit \$\endgroup\$ – PlasmaHH Nov 3 '16 at 12:35
