This is to fasten a panel to a wall. The device comprises a male member to engage on the panel and a female member to engage on the wall. For its engagement on the periphery of an aperture of the wall having a contour having two crenels facing each other and two circle arcs facing each other and each extending from one to the other of the crenels, the female member comprises a butt enabling the angular position of the female member to be indexed in relation to the wall, in order for an actuating part of the female member to be turned towards an outside edge of the wall. The assembly comprises the fastening device, the wall and the panel. Advantageously, the assembly also comprises a tool capable of insertion between the wall and the panel to reach the actuating part of the female member.

A fastener for fixing a mat to a carpet includes a female element having a cap and a female eyelet to sandwich a mat therebetween. A base element is engageable with the female element and includes a carpet holding arrangement for holding a carpet. The base element includes an enlarged head provided with an annular groove. The female eyelet includes at least two studs projecting inward, and deformable arms each of which extends between two adjacent studs transversely to a direction of pushing the head of the base element into the female eyelet. Each arm has a central portion disposed in the annular groove when the female element is engaged with the base element.

A locking device for a cover and the like which is locked by a first push and unlocked by a second push includes a case () which has at a work face (), an elastic leg () provided with a follower (); and a sliding member () which has, parallel to the work face (), a planar cam surface () from which projects a central island () about which is formed a cam track for the follower (). On the first push, the follower () passes from its free position (R) to its captive position (V) by a first path on the cam track and, on the second push, the follower () passes from its captive position (V) to its free position (R) by a second path distinct from the first path.

An article has a tubular barrel (4) formed with a cavity and a catch (6) extending within a cavity window (5). A threaded rod (22) is adapted to be received in the cavity. In the absence of stress, the catch (6), in a rest position, has a wedge (12A) projecting inside the barrel (4). This wedge has a first inclined face (14) which faces the inlet opening (13) in the barrel and is inclined theretowards and towards the outside, and having a second face (15) which is opposed to the first and inclined in the opposite direction from the inlet opening (13) towards the outside. The catch (6) is adapted to tilt resiliently towards the outside when a force normal to the first inclined face (14) is applied thereto and to tilt resiliently inwards when a force normal to the second inclined face (15) is applied thereto. The article is used, when made of plastics material, with a threaded metal rod.
