The device is designed for a window screening structure. It contains a first pair of brackets (6) for assemblying on every pair of opposite parallel frame surfaces (2) of the structure of the case and a second pair of connection elements (7) which are gripped by the screening structure. Every bracket (6) and every element (7) contain gripping devices (11, 16) for a releasable sliding engagement of a connection element with a bracket. Every bracket (6) or every element (7) have a flexible device gripped by a support (19) to them for holding each other. Brackets (6) are identical standard elements containing a relatively flat front part, projecting out of the frame surface (2), and gripping devices (11, 12) formed by a pair of opposite parallel side edges. Every element (7) is in the form of a flat, block-like, element supplied with an open cavity surrounded by small legs (13, 14) forming fastening devices (15, 16) which are engaged by the gripping devices of the brackets. 15 claims, 1 figure
