Abstract: Packaging, especially for watch straps, having two arms for maintaining a strap, such that the two arms may pivot with respect to each other into a plane containing an end of each of the two arms, and associated with the journal axis is an opening whose cross-section is substantially equal to that of a conventional watch case. Each arm can have a U-shaped cross-section, and the arms are arranged such that when they extend one against the other, the assembly forms a closed case. Also, each arm can include an element for maintaining a corresponding end of the strap.
