Henry, I've devised a (very) dirty solution:
duplicate residue 1 as nr. 9
The trace or cartoon is very sharp at the connection, so things get
better if we shift the residue numbering, such as making
1 -> 6
2 -> 7
3 -> 8
4 -> 1
5 -> 2
6 -> 3
7 -> 4
8 -> 5
9 is a copy of the new residue 1 (former 6

It (sort of ) has D2 symmetry, and is therefore dissymetric in its own right

Well, it is not based on residue numbering.
A possible way to deal with this ould be to parse the pdb information
in LINK records.
Henry's file (2HK4.pdb) has them:
LINK P C A 1 O3* T A 8
LINK P C B 1 O3* T B 8
the bonds are there; it's just the cartoons that are not.

Hi Henry
Nice molecule! I had only known cyclic DNA molecules as in
"circular" DNA, e.g. procariotic DNA and plasmids. Chemicaly there is
not much difference.
I don't know the exact code being used fior calculating and rendering
cartoons et al., but I guess it is based on phosphorus IDs and
