    hi there
    welcome to EP :)

    they are filter inductors ..... a length of wire with a couple of ferrite beads

    Thanks for info, now i would like to ask some further advice. Is there any possibility i could join them back where they belong to? If not, i would like to ask for advice on what do i exactly need to buy so i can get identical part.

    you would need to remove the solder from over the holes on the bottom side of the board
    then see if there is enough wire length coming out of them to pass through the boards holes and be soldered

    If not, then you could try to unglue the beads and put them over new lengths of wire that have enough length to be soldered

    I'm a bit confused how would i unglue them, do you mean i should take them apart somehow? I don't see how they are glued together.
    I don't have much experience on electronics, so i have to ask stupid: Should i get some tin and attempt to solder these back in?

    look closely at them ....
    they are glued with black stuff across the tops where the wire links between them.
    its quite possible that you may be able to just gently ring bark around the tops with a small blade and slide the ferrite beads off the wire
