Abstract: A snap-acting latch mechanism for sliding doors is disclosed in which a latch bar is rotatably mounted and extends from a latch assembly for insertion into a keeper assembly. The keeper assembly is formed for cooperative engagement of a head portion of the latch bar to retain the same against withdrawal and yet the latch bar can be rotated to a position enabling withdrawal from the keeper assembly. In the improved mechanism of the present invention the keeper assembly includes a pair of resilient band means mounted in side-by-side, spaced apart relation so as to snap into engagement behind the head of the latch bar and yet enable withdrawal of the latch bar upon rotation of the head by 90.degree..
