A body (1) for accommodating rechargeable batteries is connected to a plug (4) by a ball joint having limited motion. The body (1) includes a seat (3) for a ball (7) fixed to the plug (4) by a shank (5). A slot in the body for the shank (5) extends over an arc of 90 DEG so as to permit rotation of said plug (4) between a position of alignment on the device body (1) (phantom lines) and a connection position orthogonal to the former (solid lines) whereat the plug (4) projects laterally out of the body (1) for connection to an electric socket. A pin (16a,b) diametrically led through the ball (7) is guided within grooves formed internally of the seat (3), thereby to allow rotation of the plug (4) around its shank (5) between the connection position proud of the device body (1) and a further connection position orthogonal to the former. <IMAGE> |
