Abstract: An identification snap for attachment to woven material such as clothing includes a first plate member bearing identifying indicia on an outer surface and a post projecting from an inner surface, and a second plate member including a centrally disposed orifice extending from an inner face to an outer face, the orifice being defined by a substantially frusto-conical wall which converges toward the inner face. The orifice is sized to receive the post of the first plate member in an interference fit so that when the first plate member is placed against the fabric of a garment with the post extending through it and the second plate member is placed on the opposite side of the fabric, the post can be received within the orifice, thereby joining the first and second plate members and clamping the fabric therebetween.
