What model Rolleiflex do you have? Ones earlier that the 3.5 or 2.8E have the arrangement that John Koehrer describes above. Later models use metal "scissor clips". I should be possible to use the metal split ring that comes with the Gripper strap with either type of fitting or, possibly, to thread the end of the nylon strap through either one. I use a Domke Gripper strap on my 2.8E, but I already had a set of scissor clips, from a worn out leather strap. I had those riveted to the ends of a generic nylon strap, cut off pieces a few inches long, and buckled those to the Domke strap. This a a more elegant way to go but isn't really necessary.
