HP-32E metallic battery clip missing

[tuxfish]

Hi,

in my HP-32E (spice series) the "metallic battery clip" that holds together
two AA batteries and connects them to create 3V/2.4V is missing.

Instead of combining two AA cells with tape and aluminium foil
(thus simulating an HP-82109A pack) I would prefer this more
elegant "metallic battery clip" solution.

What is the correct technical term of this "metallic battery clip" ?
Is there a part-number for it ?
Does anyone has a source for it ?

Best Carsten
