Abstract: Embodiments of the present invention provide a connection system with a projection on a first connector and a cooperating cavity on a second connector to provide push-through connection of the connectors in first and second configurations in which the projection extends to first and second depths respectively within the cavity, wherein one or more of the projection or cavity is movable in two dimensions perpendicular to a longitudinal axis of the projection when received in the cavity, wherein the first and second connectors have cooperating locking surfaces arranged to engage each other when the projection is received at the second depth to prevent said movement in two dimensions and wherein the cooperating locking surfaces do not engage each other so as to prevent said movement in two dimensions when the projection is received at the first depth in the receiving cavity.

Abstract: Disclosed is a connector assembly, which includes a metal base which defines a housing cavity arranged to receive the end of a male connector, a resilient interface element inside the housing cavity, and a metal clip inside the housing cavity by the resilient interface element. The metal clip engages removably with the end of the male connector inserted into the housing cavity to connect the metal base to the male connector. Also disclosed is a resilient interface element providing an interface between a male connector and a metal base defining a housing cavity to receive the end of a male connector, as well as a kit of parts. Such kit contains a metal base defining a housing cavity receiving the end of a male connector, a metal clip arranged to be capable of engaging removably with the end of the end of the male connector, and a resilient interface element.

Abstract: A method of installing panels includes temporarily securing un-upholstered panels in place on an underlying support and marking the underlying support at each of a plurality of panel clip locations on the panel. The panel is removed from the support structure for upholstering. The support structure is drilled at the marks to provide a hole to receive a socket component, and a socket component is driven into each of the receiving holes in the support structure. The socket component includes a cup open to at least one end, an external thread for engaging the support structure, and a constriction in the cup spaced away from the bottom of the cup. A plug component is secured at each of the panel clip locations on the panel, the plug component having a protruding portion to engage in the socket. The upholstered panel is lifted into position and the periphery is pressed into place to engage the protruding portions of the plug components within the cups of the sockets.
