UML14 — UML 2 Super / Classes /

on page 115 (section 7.15.3) when talking about the Notation of an
interface, the third paragraph (between figure 59 and 60) says:
"
The usage dependency from a classifer to an interface is shown by
representing the interface by a half-circle or socket, labeled
with the name of the interface, attached by a solid line to the
classifier that *implements* this interface (see Figure 60).
"

And I think it should say:
"
The usage dependency from a classifer to an interface is shown by
representing the interface by a half-circle or socket, labeled
with the name of the interface, attached by a solid line to the
classifier that *requires* this interface (see Figure 60).
"
