Fixed Downlights - How to connect Junction Box section?

[Guernica]

Hi,

Yesterday I bought some fixed down lights from Wickes (for a bedroom I'm updating).

I've opened up the box, and there are 4 components for each downlight: body, clips, bulb and socket (with junction box).

The only thing I'm not sure about is how the socket/junction box section attaches to the body of the light. In the following pic you can see the metal arm that secures the junction box, its end, with 2 prongs, and the main body of the light where the spring are attached. (The diagram that's in the box shows the metal arm screwed to the body, but there is no screw, or screw hole.)

Any ideas?

Push the middle prong through the middle of the spring.

Cheers Stivino - I thought that might be the case!
