Quick tiling newbie question

[snazpizaz]

Hi - tiling newbie here

A couple of tiles have come loose and i want to re-attach them but don't know the name of the equipment to buy. (See image)

1 What are the name of the little plastic bits which help space tiles apart when refixing tiles ?
2 Apart from tile adhesive and grout - is there anything else i should buy to complete this job ?
3 Is there a tiling store chain for tilers like 'Screwfix' for plumbers in the UK / London ?

cheers

You dont need any equipment. you take the loose tiles off and clean up the adhesive and grout, and glue them back and grout them with your finger. But when tiles pop off like yours it means there's something wrong with the background, usually its water getting behind the tiles.
Water can get behind through the grouting.

Leave the tiles in a bucket of water for a day. The adhesive will go soft and you can scrape it off. This will ensure that you can butter the tile with new adhesive and fix them level with adjacent tiles. A notched trowel will help. If, as Wes says, the substrate is damp let it dry ot get a heat gun and gently dry it before trying to re-attach them.

Don't bother buying some spacers just to refit a couple of tiles. A few matchsticks or some thick cardboard will do the job just fine for you.

Is there a practical reason for having these spaces between tiles which then have to be filled with grout?
Or is it 'Cosmetic'?
