Abstract: A connecting means adapted to releasably fix or release a first element (4) and a second element (5) includes a locking pin (1) which is moveable by remote activation means between a locked position, in which leg (8) expands wall (9) into recess (10), and an unlocked position. The remote activation means may be magnetic, electromagnetic or any other suitable means. There is no permanent material connection between the pin (1) and the remote activation means. A method of fixing or releasing first and second elements by remote activation means is also disclosed. The invention further provides an embodiment where the first element is a first panel and the second element is a second panel. The first panel has means (166 or 169) which co-ordinate with means (165 or 170) on the second panel.

Abstract: A connecting means adapted to fix or release a first element (4) and a second element (5) includes a locking pin (1) which is moveable to remote activation means between a locked position. In which leg (8) expends wall (9) into recess (10), and an unlocked position. The remote activation means may be magnetic, electro-magnetic or any other suitable means. A method of fixing or releasing first and second elements by remote activation means is also disclosed. The invention further provides a first element having first means (166) adapted to cooperate with second means (165) on a second element to facilitate connection of the first and second elements. A method of manufacturing the first element includes the steps of depositing discrete amounts of setable material on a surface of the first element and inverting the element to permit the material to set under the influence of gravity. A method of reducing the spacing between first and second elements by remote activation means is also disclosed.
