A fastener device is disclosed, which comprises an inserting part, a socket having an insertion aperture and an intermediate filament connecting the inserting part and the socket. The inserting part, which can be inserted into the socket from either of two insertion directions of the aperture, has at least one tongue, which has a suitable elasticity and can expand in radial directions relative to the axis of the inserting part under its condition free of any force application. The aperture of the socket has a face to engage and stop the socket, which is vertically provided relative to the axis of the aperture. In inserting the inserting part into the socket, the tongue undergoes contraction to facilitate its passage through the aperture, and when it has been completely passed through the aperture, the tongue restores its original condition and radially expands to abut against the engaging face of the aperture, preventing the inserting portion from being pulled out of the socket. This fastener device is formed from a synthetic resin in an integral structure.

A fastener comprising a socket having an aperture, a filament continuously extended from said socket, and an inserting part provided at the leading end of said filament and capable of being inserted into said aperture in either direction thereof and being anchored in the aperture, wherein a rigid inner flange including a guide face having the same axis as the axis of the aperture and two circular abutting faces perpendicular to said axis, said flange being formed in said aperture, said aperture thereby being symmertical about a plane perpendicular to the axis of the aperture and wherein at least one elastic tongue is formed on the inserting part, the free end of said tongue expanding outwardly in the radial direction with respect to the axis of said inserting part when it is kept in the free state and said free end of the tongue being contracted inwardly in the radial direction while it is passing through the guide face, and after said free end of the tongue has completely passed through the guide face, it returns to its original free state and is anchored to said abutting faces, whereby said inserting part is tightly connected to the socket.
