An apparatus for releasably securing a line having a cross sectional thickness and at least one free end. The fastener has a shaft dimensioned for wrapping the line around the shaft. The shaft has a pair of ends at least one of which includes: an insertion structure extending from the end that defines an insertion opening and a retaining structure extending from the end a distance greater than the cross sectional thickness of the line. The retaining structure defines a retention aperture operably dimensioned smaller than the cross sectional thickness of the line. When the free end of the line is inserted through the opening, positioned adjacent the shaft, wrapped around the shaft and positioned in the retention aperture, the line is thereby releasably secured.
