Abstract: The present application describes a method for attaching a first part (20) and a second part (30) for mechanical assembly to each other, the method comprising spraying a powder (10) of a ductile material onto the parts (20, 30), causing the parts (20, 30) to become attached to one another by agglomeration of this powder (10), the method comprising texturing at least one surface of one of the two parts (20, 30) onto which the spraying is subsequently carried out.

Abstract: The invention relates mainly to a fastening system (1) comprising a fastening part (2) and an arming part (11), the fastening system (1) can be actuated between a fitting position around the stud (34) wherein the arming part (11) holds four tabs (7, 9) of a fastening part (2) in the stressed position thereof, and a position of tensioned fastening to the stud (34) wherein the arming part (11) is connected to the fastening part (2) when the four tabs (7, 9) are in the free position.

Abstract: The invention relates to a fastening device for holding together a stack of at least two panels, comprising a female piece in the form of a clasp, and a male piece having a part in the form of a head, and a part in the form of shaft with a cross section in the form of a cam which can be axially inserted into the clasp. The device includes a component for immobilization of the male piece in the female piece which is connected with clasp and is produced in the form of finger which can be moved by deliberate action between a position of engagement in a notch of the head of the male piece, and a position of disengagement from said notch.

Abstract: The invention concerns a joining element for releasable joining of at least two plate-like, at least partially overlapping parts in a joining region. The element has a cover mounted on the parts being joined, and a spring-loaded clip that passes through the cover and the parts being joined, forcing the cover against the parts.
