(57) A guide groove element for the anchorage of a screen curtain, preferably placed vertically
on the outer side of a building, carried out of a housing, in which a guide groove
(2) is carried out with a centre line (X) coinciding with the direction of gravitation,
whereat the guide groove (2) ends in the shape of an inverted heart-like groove (3),
whereat the outer wall of the heart-like groove (3) is formed by the housing of the
element and the inside wall of the heart-like groove (3) is formed by a central element
(4), whereat the central element (4) comprises a movable leg (41) that forms an obtuse
angle with the centre line (X) of the guide groove (2), a fixed leg (42) running parallelly
to the centre line (X) of the guide groove (2), and a recess (43) disposed opposite
to a heart-shaped bulge (8) formed on an inner surface of the outer wall of the heart-like
