When the plug body is locked to the associated socket by the locking mechanism, the cam member is externally driven to cooperate with the tapered surface, thereby moving the main cylindrical member and the inner cylindrical member relative to each other in the axial direction of {HEAD ~ the housing sections} and bringing the plug body and rear cylindrical member into {TAIL ~ contact} with each other in the axial direction thereof
