Abstract: The hook includes a body having a receiving space for receiving the journal and, within the body, a clip for coupling to the journal and an actuator for actuating the clip. The clip includes a semi-cylindrical wall, two flaps and two hinges for pivotal hinging of each flap to a respective one of the walls. The clip has a closed position in which the flaps have come towards each other to form with the wall a bearing for the journal, and an open position in which the flaps are separated for freeing and insertion of the journal from/into the receiving space. The passage from one position to the other is actuated by the actuator by pressing the journal on the wall.

Abstract: The fixing device includes a base including elements for pivotal mounting of the ring; a foot carried by the base, including a first pair of lugs extending from the base, a crossmember disposed between the lugs, and a second pair of lugs connected to the base; and a rod adapted to enter a bore provided through the base; each of the lugs having a shoulder over the whole of the width of the lug, the shoulder forming a transition between a first section of the lug and a thinner second portion. The support includes the above device and a ring retained in the pivotal mounting elements.

Abstract: The fastener comprises a first part having a stem and a head attached to one end of the stem, and a second part having two elastic feet and a plate from which the elastic feet project transversely, the stem being adapted to slide in an opening formed in the plate, the fastener being adapted to assume a waiting position in which the first part is held in the second part by means of the stem passing through the opening and clamping said plate between a stop surface and a tooth; a locking position; and an unlocking position.

Abstract: The hook comprises a body having a housing for receiving the journal and, within the body, a clip for coupling to the journal adapted to delimit said housing and means for actuating said clip. The clip comprises a semi-cylindrical wall, two flaps and two hinges for pivotal hinging of a respective said flap with respect to said wall. The clip has a closed position in which said flaps have come towards each other to form with the wall a bearing for the journal, and an open position in which the flaps are separated for freeing, from said housing, and insertion, into said housing, of said journal, the passage from one to the other of said positions being actuated by said actuating means by pressing of said journal on said wall.

Abstract: A rivet (1) includes a bearing head (2), a pulling stem (3) and an insertion body (4). The insertion body (4) includes at least two longitudinal flat surfaces (13) interrupting a notched portion (14); and at least two elastic feet (15) each having a first end elastically joined to the insertion body (4) and a second end which is free. Each of these elastic feet (15) is adapted to adopt a folded position in which it is folded along the insertion body (4), on one of the flat surfaces (13), and a tightened position in which it is arranged transversely of the general orientation of the insertion body (4). The bearing head (2) has at least one slot (9) enabling the head to deform radially.

Abstract: Fastener (1) includes a head (2) and a body (3). The head (2) has a transverse stop (5) able to bear on the first piece (23). The body (3) has a first spacer (10) and a second spacer (11), coaxial and disposed in line with each other in an axial direction. The first spacer (10), adjacent to the head (2), has a diameter greater than that of the second spacer (11) which extends starting from the first spacer (10), on the opposite side from the head (2). Each of the spacers (10, 11) has at least one lug (13; 18).
