A plastic identification band for milking cows is formed as a strap of a width to receive identifying indicia and a length for attachment to and about the leg of a cow. A rectangular buckle at one end has a bottom wall coplanar with the strap and an upper wall defining an opening to receive the outer end of the strap. The bottom wall of the buckle includes a plurality of upwardly facing teeth extending longitudinally of the buckle. The strap has a plurality of similar teeth on the underside thereof. The upper buckle wall is a flexible wall which is deflected slightly inwardly toward the bottom wall and has a narrow, longitudinally extending ridge projecting inwardly from the upper buckle wall within the buckle toward said buckle teeth to hold the strap teeth firmly engaged with the bottom wall buckle teeth upon insertion of the strap into the buckle.
