You can delete it using the Pseudobond Panel (in menu under Tools… General Controls): click “missing segments” on the left to choose it, then click the “close” button on the right (different than the Close button at the bottom, which closes the panel).
However, this does not solve your problem: Chimera already considers those atoms to be covalently bonded because of the CONECT records in your file, and will not let you add another bond. The only reason it was shown as a pseudobond instead of regular bond is that the distance was abnormally long (>3 A).
If you want to add a bond between the atoms you should remove the CONECT records from your PDB file before opening. Then there will not be any covalent bond between the atoms yet, so you can select and bond them.
I hope this helps,

But I have problems with deleting the pseudobond, I have not found a way to do it. Could you help me out?
