12v Lighting Safe Cable Connection Method?

Can someone guide me on a safe method of connecting the output from a low voltage transformer to the feed in wire of a lighting track system?

The feed in cable (60cm long) is 20cm too short to reach the short (15cm) cable on the transformer. The transformer has no-body connectors and the feed in socket is also sealed so this means I'll have to add a section of cable to complete the 1m cable run and have 2 connections..which feels like a bodge job. The existing cables themselves are pretty thin (1mm) so I'm thinking a thicker cable such as 1.5m two core would theoretically be better (less resistance). If correct, what would be a safe method of connection? I know there are quick connectors available but considering the different wire gauges then perhaps choc blocks would be more effective?

Perhaps I'll just have to buy a new transformer but I've got 7 to wire up, all with the same problem

Wire nuts (as shown in the first pic) are perfectly acceptable for the job.

Cap crimps (as shown in second pic) are my personal favorites.

Thanks PJMax - I'll get some. So you're not concerned by the number of joins in the cable run or joining a rigid wire to a flexible multicore (or whatever its properly called)?

Wirenuts will have a range of wires they are rated for. It will depend on the size of wire and how many. For example the reds we use is something like 3 #18 - 3 - #10 which is quite a large range. Solid wire and stranded wire does not matter for wirenuts

Another option is push in connectors In-Sure™ Push-In Wire Connectors but be sure to check the wire sizes acceptable for them as well.

Low voltage can be spliced as many times as necessary. You can also connect solid wire to stranded wires with no problems. Tolyn mentioned push in connectors which are good connectors and great time savers but they don't always work well with stranded wire.
