Morphology

sash + fastener

This is a straightforward noun–noun compound: the meaning can be directly derived as a fastener used for a sash (window frame). It follows regular English compounding patterns and is not idiomatic or metaphorical, so a B1 learner who knows 'sash' and 'fastener' should understand it.

Etymology

Sash fastener comes from the parts of an old-style window: a sash is the sliding window panel and a fastener is a small catch or hook that holds the sashes together. Picture a little metal hook clicking over the other sash to 'lock' the window, and that image explains why the name means a device to keep a window 'closed'.
