SailorJ,

+ 1 on the cyanoacrylate ('Superglue') glue.

Glue the piece back on to the coticule with the 'Superglue', sandwich the coticule between two (2) sheets of cling film, and put some weights on top or clamp well.

Let the glue 'set' for a day or so, then flatten coticule as normal.

There is some good information here :

Have fun

Best regards
