Extracting device for a plug (10) at the end of an electric cable connected to an electric appliance, which plug (10) may be plugged into a socket (16). The extracting device comprises at least one elongate, alternatingly displaceable piston (14) which has a longitudinal piston-portion located within the plug (10), which longitudinal portion and the plug (10) have a common longitudinal axis. The piston (14) has two main positions, a first main position in which the front end (14') of the piston (14) is withdrawn in relation to the outer ends of the projecting contact pins (18, 18') of the plug (10), and a second main portion, in which said front end (14') thereof is located substantially just as far in front of the front end surface of the plug (10) as the outer ends of said contact pins (18, 18'). The piston (14) has an activating device (24, 28, 26, 26') arranged thereto, which, itself, is arranged to be activated automatically and maybe by remote control, to activate, thereby, the piston (14) to effect a displacement of this from said first main position into said second main position. During said displacement the piston (14) exerts a pressure against the socket (16), so that the contact pins (18, 18') of the plug (10) are extracted from the corresponding bores (20, 20') of the socket (16). |
