Strictly speaking, chromatids aren't attached; they grow that way. They are, however, formed during Prophase of mitosis and Prophase I of meiosis.

The chromatids are attached to each other at the Centromere. Hope that helps have a nice day.
centromere
The centromere is the most condensed and constricted region of a chromosome, to which the spindle fiber is attached during mitosis.
When sister chromatids are joined together they are held together by proteins, which make up the centromere. The two chromatids together make up a chromosome.
Pairs of chromosomes are not attached. Before mitosis chromosomes replicate themselves, these twin identical chromosomes are attached at the centromere. before cell division the cell has 46 chromosomes (23 pairs) but has 2 copies of each individual chromosome called chromatids,(making a total of 92 chromosones, 46 for each daughter cell) which are joined at the centromere giving the characteristic X shape. Pairs are not joined, chromatids are.
The chromatids are attached to each other at the Centromere. Hope that helps have a nice day.
The Centromere, use the wiki article for further reading.
The two chromatids of a chromosome are attached at a point called the centromere. It is the point which it is attached to a spindle fiber during the process of cell division.
