A handle (10) attached to a printed circuit board (7) for manually inserting and removing the board into and from a rack has a pivotable lever (13,14) at each end of an elongate member (11); to disengage a multi-pin plug and socket connector (8,9) when it is desired to remove the board from the rack, the levers (13,14) are rotated to engage cross-bar members (1,2) of the rack, exerting moments on the handle (10) tending to withdraw the board from the rack. To inhibit rattling of the levers (13,14), when the rack is subjected to vibration, and other undesired rotation of the levers, recesses (25,26) are provided in the elongate member (11) respectively adjacent the levers, the recesses receiving respective resiliently deformable elements (27,28), such as cylinders of neoprene rubber, which co-operate with the levers to urge them towards their inoperative positions. |
