A snap-in hinge for an enclosure having provisions to prevent binding of the attached cover. The hinge includes at least two legs extending from the ends of a curved portion of the hinge and a blocking means integral with the corresponding hinge slot located in the enclosure. The legs, extending from the ends of the hinge, provide a smooth and continuous bearing surface for the enclosure cover, thereby preventing the enclosure cover from being trapped under an extended portion of the hinge which might be used to prevent over insertion of the hinge into the hinge slot. The blocking means of the corresponding hinge slot engaging parallel edges of the curved portion on the hinge prevents the hinge from being over inserted into the slot and thereby binding on the portion of the enclosure cover captivated by the curved portion of the hinge.
