    Abstract: A fastening device to join together panels comprises a body (12) that has a spreader (32); a U-shaped spring (14) with arms (47, 48) provided with outward facing gripping means (47'', 48'') protruding from said body and drawn together in a resting position; a cam-type operating element (18) rotatable in said body. By rotating the cam element, the spring is movable between a resting position with the arms close to each other, in which it leaves said panels free and an engagement position with the arms spread apart, in which it engages the walls of a hole in a panel, and vice versa. The body (12) has an elongated cylindrical shape and comprises an internal housing (26). A slide element (16) is received inside the housing, is moveable for an axial distance along it, and has means (44) for engaging the spring. The cam element (18) is received in the body and in the slide to operate the movement of the slide between said resting position of the spring and said working position of the spring and vice versa.

    Abstract: The device comprises a hollow box-shaped container-guide (12) inside which a shaft-like fastening member is rotatably received, said member being provided with at least one projecting, eccentric tongue (24), which is inclined with respect to the axis (a) of the shaft, or is preferably shaped according to a section of a helicoid. The fastening member is rotatable between a position in which the locking tongue/s (24) is/are contained inside the hollow container (12) and a position in which it/they projects/project from it to grip into the walls of a hole which receives the container, or against the wall of a panel. A head (22) of the fastening member (14) can be manoeuvred from the outside and has two abutments which collaborate with abutments integral with a head (18) of the container in order to define the completely retracted position of the tongues and the completely extracted position of the same. The container can be realized in various forms.
