Abstract: A press fastener comprising a plug body connecting with a slotted body. The plug body contains an elastic tongue part for extending into the slotted body. The tongue part contains a climbing angle positioned at the end thereof to hook the plug body to the slotted body when the climbing angle of the tongue part extends along an angled receiving groove of the slotted body, thereby stressing the tongue part, and into a center cavity of the slotted body. The central cavity is of such dimensions to allow a press groove to be supported therein to allow unhooking of the plug body from the slotted body when pressure is exerted thereon.
