A clasp or clamp secures a string or rope, such as made from stretch wrap, to an object such as in securing an object to a pallet for shipping. The clasp or clamping device readily secures one end of the string and allows for tightening of the string through pulling a second end of the string through a second portion of the clasp or clamping device. The second end of the string can be tied off or secured on the second portion of the clasp or claiming device. The clasp or clamping device further includes at least two protrusions extending from one of the first end and the second end, the at least two protrusions defining a space there-between. The space between the at least two protrusions includes a narrow portion to impede slippage of the string.
