A plug of a twist latch is comprised of a main body, knob body and fixing plate. The main body has a shaft-bearing portion provided on a base, whose outer shape is an ellipse and having a circular hole portion inside. An upper portion of the shaft-bearing portion is a contracted diameter portion while a lower portion thereof is an expanded diameter portion. Several protruded ridge portions are provided on the expanded diameter portion to form an engaging portion. The knob body has a knob portion of an ellipse-trapezoidal shape having a shaft portion extended from a bottom face thereof. The shaft portion is divided along an axis thereof. This shaft portion is rotatably fit into the shaft-bearing portion. The fixing plate has a hole portion in which the shaft-bearing portion can be inserted, and is formed with fitting portions that can be fit onto an engaging portion, on the periphery of the hole portion. When this plug is mounted on a cloth, the shaft-bearing portion is inserted from a back side of the cloth. Upon use of this plug, the knob body is inserted into a socket provided on a mating cloth and the knob portion is turned so as to engage the plug with the socket. Thus, the plug can be attached from a back side of a cloth such as a bag, and the twist latch has a tough structure and a good appearance and does not easily slip out of the cloth. |
