A security hard tag, uses an attachment clip to couple to an article, such as but not limited to clothing, to be protected and which can only be released from the article by use of an authorized detacher that is inserted into the security hard tag. The attachment clip may include various types of locking mechanisms on its two ends, one end which is permanently secured within the security hard tag housing and the other end which is releasably secured within the housing. Before being releasably secured within the housing, the one end is inserted through or around a portion of an article, or through a security tag loop attached to the article, and then that end is locked into the housing. The detacher uses a cam, either located on the detacher itself or positioned within the security hard tag housing, to interact with the one end of the attachment clip to release the locked end. The housing also includes a security element that may comprise EAS (including AM, RF, EM and microwave), RFID (including LF, HF and UHF), benefit denial (e.g., ink-filled or dye-filled capsules) or any combination thereof. A preferred embodiment of the security hard tag uses all non-ferrous components including its locking mechanism. The non-ferrous composition of the security hard tag, along with the attachment clip design, forms a security hard tag that is strong and lightweight, thereby providing a low impact presentation of a security hard tag with an article.
