How to make a wire/fiber splice in creoShematcis 2.0

Hi everyone,

I am new to Creo shematics and I have troubles making a simple splice on a wire. I precisely followed the indications in the doc page "To Insert a Splice" with no success; the cursor does not become "T shaped" as it is supposed.

I use creo schematics 2.0.

Any help/advice would be greatly appreciated.
