Word for “puts pressure” around an object (intransitive verb)

Example:

The noose around his neck ________ even more.

or

The noose around his neck increasingly ________.

Compresses perfectly conveys the meaning of exerting pressure, however, it is a transitive verb and would not fit in any of the sentences. Same for constricts.

Smothers is not what I’m looking for because it’s limited to the example of a noose but I want a word that would work more generally, e.g., in the case of a handcuff around a wrist.

Tightens is the best word I could think of. However, it doesn’t perfectly convey the meaning of exerting pressure, because, in this case, it would be reflexive (the noose tightens — the noose is both the subject and implied object of the action), while I prefer a word which clearly implies that the pressure is being put on the neck or wrist.
