ABSTRACT:
An electric plug includes two locating blocks aligned at two sides of the housing thereof to pivotally hold a substantially C-shaped pull ring. The pull ring has two pivot holes aligned at the ends thereof and respectively pivotally connected to the locating blocks by a respective pivot bolt that has a head stopped outside the respective pivot hole. The heads of the pivot bolts each have a diameter greater than that of the pivot holes so as to prevent disconnection of the pull ring from the housing.
