End connectors are small silver or gold findings that are sort of “U” shaped with a ring on the end.

To use them slip the cord into the “U” and with a smooth plier fold one half in over the cord.

Just like above.

Fold the second half over and crimp tightly.

Then you can add a clasp or charms… depending on the project. End connectors are great to use with all sorts of cording and ribbon.
