An inflatable article fastener apparatus includes two lengths of flexible cord. First and second locking structures are connected to the two lengths of flexible cord, wherein the first and second locking structures are located at a spaced distance apart from one another on the two lengths of flexible cord. An eyelet portion is formed between the first and second locking structures and at least one non-eyelet portion is formed outside of the first and second locking structure. An end of the at least one non-eyelet portion is insertable through the eyelet portion to form a collapsible loop capable of constricting a neck of an inflatable article positioned within the collapsible loop. A locked position of the collapsible loop is achieved when the first locking structure is pulled through the eyelet portion.

Disclosed are an eyelet member and a method of manufacturing the same. The eyelet member includes a first decoration unit, a second decoration unit having at least a portion inserted into the first decoration unit, and a stopper coupled to the first decoration unit and configured to allow the portion of the second decoration unit to pass therethrough, and the stopper is elastically in close contact with the portion of the second decoration unit and fixes the second decoration unit so as to prevent the second decoration unit from moving in a direction opposite an insertion direction thereof.

A cord lock includes a female member including first cord insertion portions through which a cord can be inserted to pass; a male member capable of moving in and out from an opening of the female member, and including second cord insertion portions through which the cord inserted to pass through the first cord insertion portions can pass; and an urging device provided between the female member and the male member to provide an urging force in a direction wherein the male member protrudes from the opening of the female member. The second cord insertion portion of the male member and the urging device are located adjacent to each other, and on opposed faces of the female member and the male member along an insertion direction of the cord, straight portions which can carry out at least a line contact are provided.
