Problem identifying cable or adapter to connect TV to Soundbar

Description of problem

Can't connect Bush 24" HD LCD TV (LED24265DVDCNTDW) to Samsung Soundbar (HW-M360).

Other relevant info

Samsung Soundbar has a standard TOSLINK optical input. Bush TV (UK brand) has what the manual identifies as a SPDIF output. Looks about the size of a 3.5mm audio jack. Has "SPDIF" written on top, "Co-ax out" underneath.

When this issue began

New

Recurring issue

Yes

Cause/Steps to recreate the issue

Standard optical cable will not fit TV.

What I've tried so far to resolve the issue

Toslink to mini-toslink will not work. Mini-toslink cable doesn't quite fit and doesn't engage in the TV connector.

Standard TOSLINK does not work obviously.
