Claim Text:
1. A connector system of a structural framework, the system comprising a socket device and a plug device that can be coupled to the socket device, the socket device including an outer socket housing and a socket member in the socket housing, the socket housing having a coupling hole bordered by a retainer wall, and the socket member having a socket hole of non-circular cross-section, the socket hole disposed in a distance behind the coupling hole, the plug device comprising a plug member and a coupling sleeve, the plug member including a plug body that is cylindrical slidably inserted into the coupling sleeve and that includes an exposed plug end portion axially projecting out of a free end portion of the coupling sleeve and having a non-circular cross-section designed to fit into the socket hole of the socket member, the free end portion including at least one radial locking nose radially projecting outwardly on an outer peripheral surface of the free end portion of the coupling sleeve and having a limited circumferential width equal to or smaller than a half of the circumferential length of the outer peripheral surface of the free end portion, the coupling sleeve designed to be axially displaceable relative to the plug member between a release position and a coupling position, wherein the free end portion of the coupling sleeve inclusive of the locking nose axially fits through the coupling hole of the socket housing when the coupling sleeve is in the release position, and the retainer wall includes a locking portion radially projecting by the radial projecting length of the locking nose into the coupling hole, and wherein the plug body and the coupling sleeve include axial cam members engaging each other to cooperate upon a rotation of the coupling sleeve for said axial displacement of the coupling sleeve between the release position and the coupling position so that the plug end portion of the plug member can be fitted into the socket hole of the socket member while the free end portion of the coupling sleeve inclusive of the locking nose is inserted through the coupling hole into the socket housing, and the locking nose is displaced towards and against the locking portion of the retainer wall of the socket housing upon and during a relative rotation of the plug device and the socket device.
