A link 
End names, aggregation, composition, navigability, and other adornments can be shown on the link ends or roles, but because links are instances, their ends do not show multiplicity. A link can also have a stereotype to indicate a particular kind of implementation.
Name a Link shape and add other property values
Open the element's UML Properties dialog box by double-clicking the icon that represents the element in the tree view or the shape that represents the element in a diagram.
Tip: Control which property values display on a shape in a diagram by right-clicking the shape, and then clicking Shape Display Options. In the UML Shape Display Options dialog box, select and clear options to display or hide property values.
