A device for opening and closing a pivoting wing, comprising: a stationary support intended to be attached to a fixed frame, a slide movable relative to the stationary support along a rectilinear direction between an open wing position and a closed and locked wing position, a pivoting arm articulated to the stationary support about an articulation axis, and having a distal end intended to be connected to the wing, a transmission mechanism associated with the slide and the arm, comprising an essentially L-shaped cam engaged by a control pin, the transmission mechanism being configured to transform the rectilinear movement of the slide along said rectilinear direction into a pivoting movement of the arm about said pivot axis.
