PCT No. PCT/JP97/02920 Sec. 371 Date Aug. 4, 1999 Sec. 102(e) Date Aug. 4, 1999 PCT Filed Aug. 22, 1997 PCT Pub. No. WO98/45903 PCT Pub. Date Oct. 15, 1998An automotive battery plug (1), once fitted in a cigar lighter socket (111), is retained therein with proper retentive force. When it is pulled out of the socket, the retentive force decreases, allowing ease in the removal of the plug (1). A slider (25, 31) slidable in a plug housing (2) has on its either side surface a support portion (25a) and an inclined portion (25b) forming a slope (26) contiguous to the support portion (25a). When a return end portion (17b) of each leaf-spring contact piece (17) abuts with the support portion (25a) of the slider (25), a contact portion (17a) of the contact piece (17) greatly protrudes from the periphery of the plug housing (2) through an opening (19), permitting the battery plug (1) to be fitted and held in the cigar lighter socket (111) with suitable retentive force. When the battery plug (1) is pulled out of the cigar lighter socket (111), an operating knob (24) in a grip (22) is moved rearward, by which the slider (25, 31) also slides, causing the return end portion (17b) to slide down the slope (26) and go into the plug housing (2). In consequence, the contact portion (17a) of the leaf-spring contact piece (17) retracts to its inner position of protusion nearer to the opening (19), decreasing the plug retentive force and allowing ease in puking out the battery plug (1) from the cigar lighter socket (111).
