Abstract: The invention concerns a fastener comprising a head and a foot comprising a rigid core and three curved flexible wings each joining said rigid core along one side, having opposite a face of said core an inside surface bordered by a longitudinal edge and by a transverse edge, and having an outside surface respectively tapering towards a pointed end which is an opposite end to said head and towards said transverse edge, on respective opposite sides of an inflection plane, each said wing being configured to bend by elastic deformation towards said core; said core comprising a hub and three small walls extending radially from said hub, whereby said core is star-shaped in cross-section; and said inside surface of each said wing is bordered by a said respective small wall which is remotely opposite said longitudinal edge.

Abstract: 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 (1) which has at a work face (8), an elastic leg (7) provided with a follower (14); and a sliding member (2) which has, parallel to the work face (8), a planar cam surface (24) from which projects a central island (27) about which is formed a cam track for the follower (14). On the first push, the follower (14) 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 (14) passes from its captive position (V) to its free position (R) by a second path distinct from the first path.

Abstract: A support for mounting elongate articles, such as, tubes, pipes, conduits, cables, or the like, comprises a base member having a longitudinal extent, and a plurality of support members disposed transversely across the base member for engaging and supporting the elongate articles. The support members are longitudinally spaced upon the base member and engage opposite sides or regions of the elongate articles, such as, for example, upper regions or surface portions, and lower regions or surface portions. The upper support members comprise a plurality of deformable, resilient, and flexible blade members, and the lower support members comprise either cut-out portions formed within partition members, or similar resiliently flexible and deformable blade members.

Abstract: A snap-fastener comprises an end plate (10) and a pair of resilient tangs (11A, 11B) extending from the plate and it so disposed that when each of the tangs bends it is displaced parallel to the arms (8, 9A, 9B).
