In that case you'd better look for the term "inclusion dependency". But that is just the name of a general type of database constraint, of which foreign keys are usually assumed to be the special case where the destination is a candidate and/or a primary key. What you seem to be talking about here is the use of a foreign key to represent a binary relationship. I'm not sure why you think there should be another name for this "construct" then simply "foreign key" is not clear to me.
