An object of the present invention is to provide a plug/socket assembly in which the plug will never pull out of the socket even if an excessive pull-out force is applied to the plug. A plug/socket assembly (10) comprises a plug (20) and a socket (30) for receiving and fixing the plug (20) therein. The socket (30) includes a socket main body (31) having a plug insertion hole (311), balls (32) which are provided with the socket main body (31) in a radially displaceable manner with respect to the plug insertion hole (311), a sleeve (33) which is mounted over the outer surface of the socket main body (31) and is displaceable along the axial direction of the plug insertion hole (311), and a compression spring (34) for urging the sleeve (33) along the axial direction toward the inlet port (313) of the plug insertion hole. The inner surface of the sleeve is provided with a slide surface (332). The slide surface has first to fourth regions (P1-P4). The fourth region (P4) is shaped such that with an external pull-out force being applied to the plug, even if the balls apply a radially outward force to the slide surface, no leftward force to push back the sleeve will be produced.

What is claimed is: 1. A plug-socket assembly comprising a plug and a socket that receives and secures said plug; said socket comprising: a socket body having a plug insertion hole; a locking element fitted to said socket body so as to be displaceable in a radial direction of said plug insertion hole; a locking element-actuating member fitted to an outside of said socket body so as to be displaceable in an axial direction of said plug insertion hole; and a resilient member that urges said locking element-actuating member in said axial direction; said plug having a forward end head portion that is slidably inserted into said plug insertion hole of said socket, and a reduced-diameter portion following said forward end head portion; said forward end head portion having a slant rear surface that extends radially inward toward a rear end thereof as viewed in a plug insertion direction; said reduced-diameter portion extending rearward of said plug from a rear end of the slant rear surface; wherein said locking element-actuating member of said socket has a locking element sliding surface provided on an inner side thereof, said locking element sliding surface extends radially outward in an urging direction in which said locking element-actuating member is urged by said resilient member, so that said locking element sliding surface pressingly engages said locking element by being urged in said axial direction by said resilient member; said locking element sliding surface of said locking element-actuating member of said socket having: a first portion that engages said locking element to apply force to said locking element in order to project said locking element as far as a first position in said plug insertion hole when said plug is not inserted in said plug insertion hole; a second portion that is spaced apart from said first portion by a predetermined distance in said urging direction, said second portion being arranged so that when engaging said second portion, said locking element is positioned at a second position that is radially outward of said first position to allow the forward end head portion of said plug to be inserted into said plug insertion hole beyond said locking element; a third portion that is closer to said first portion than said second portion, said third portion being arranged such that when said forward end head portion of said plug is inserted beyond said locking element, said third portion pressingly engages said locking element that is engaged by the slant rear surface of the forward end head portion of said plug at a position radially outward away from said reduced-diameter portion where said third portion cannot contact said reduced-diameter portion; and a fourth portion that engages said locking element at an intermediate position between said second portion and said third portion and that is configured so that even if said locking element applies a radially outward force to said locking element sliding surface, said locking element-actuating member will not be forced to move in a direction opposite to said urging direction. 2. A plug-socket assembly according to claim 1, wherein a slope between said first portion and said fourth portion is less steep than a slope between said fourth portion and said second portion. 3. A plug-socket assembly according to claim 1, wherein said fourth portion extends parallel to said axial direction. 4. A plug-socket assembly according to claim 1, wherein said fourth portion is configured to face opposite to said urging direction. 5. A plug-socket assembly according to claim 1, wherein said fourth portion is a recess curved outward in said radial direction. 6. A plug-socket assembly according to claim 1, wherein the urging direction in which said locking element-actuating member is urged by said resilient member is opposite to said insertion direction; said forward end head portion of said plug having a slant front surface extending radially inward in said plug insertion direction; said socket body having: a first ball provided closer to an inlet of said plug insertion hole than said locking element; and a second ball provided closer to the inlet than said first ball; wherein the slant front surface of said plug first engages said second ball when said plug is inserted into said plug insertion hole, and displaces said second ball radially outward so that said second ball pressingly engage said locking element sliding surface between said fourth portion and said second portion, thereby displacing said locking element-actuating member in said insertion direction, and subsequently, said slant front surface engages said first ball and displaces it radially outward so that said first balls pressingly engage said locking element sliding surface between said fourth portion and said second portion, thereby displacing said locking element-actuating member in said insertion direction, and finally, said slant front surface engages said locking element and displaces it radially outward so that said locking element pressingly engages said locking element sliding surface between said fourth portion and said second portion, thereby displacing said locking element-actuating member in said insertion direction so that said locking element engages said second portion. 7. A plug-socket assembly according to claim 1, wherein said plug has at a rear end thereof a flange extending in said radial direction, said flange being arranged to clamp and secure a desired member between itself and a rear end of said socket body in a state where said locking element is pressed and engaged with said slant rear surface of said forward end head portion of said plug as inserted into said plug insertion hole. 8. A plug-socket assembly according to claim 1, wherein said plug has at a rear end thereof a flange extending in said radial direction, said flange being pressed and engaged with a rear end of said socket body in a state where said locking element is pressed and engaged with said slant rear surface of said forward end head portion of said plug as inserted into said plug insertion hole, and wherein a desired member is connected and secured to said plug. 9. A plug-socket assembly according to claim 1, wherein the urging direction in which said locking element-actuating member is urged by said resilient member is opposite to said insertion direction; said forward end head portion of said plug having a slant front surface extending radially inward in said plug insertion direction; said socket body having a first ball closer to an inlet of said plug insertion hole than said locking element; wherein the slant front surface of said plug engages said first ball when said plug is inserted into said plug insertion hole, and displaces said first ball radially outward so that said first ball pressingly engage said locking element sliding surface between said fourth portion and said second portion, thereby displacing said locking element-actuating member in said insertion direction to move said locking element to a position between said fourth portion and said second portion, and said slant front surface of the forward end head portion as inserted pressingly engages said locking element in said position between said fourth portion and said second portion. 10. A plug-socket assembly according to claim 9, wherein said socket body has a flange extending radially outward so that a forward end of said locking element-actuating member, as viewed in the urging direction in which it is urged by said resilient member, engages said flange when said plug is not inserted.
