A device for attachment to sheet material such as a tarpaulin, pool cover or bag includes an elongated bar having first and second raised mounting surfaces as well as an open ended elongated sleeve for receiving the bar and a sheet of material positioned around the bar. The elongated sleeve also has a slit which extends from one open end of the sleeve to its other open end and which enables sheet material positioned around the bar and received in the sleeve to extend outwardly through the slit on opposite sides of the bar. The generally raised mounting surfaces are sized and configured to project outwardly from the bar through the slit when the bar is received in the sleeve so that the bar can be rigidly affixed to an object such as the side of a building, vehicle or a handle.
