In Exodus 26:6, rings, taches, or clasps of gold signify the ability to use good loves to join things together. The gold stands for inner, pure loves for good. (Arcana Coelestia 9624)

Some English translations of the Word use the terms clasps, or taches of gold, and indeed Swedenborg's description of the inner meaning seems to include the idea of clasping, attaching, or joining.

Later in the story, when bronze clasps are mentioned, they mean more external -- though still good -- loves.
