Thanks Girls, so the consensus seems to be that Ive bought the correct part but am a total Wimp! The second part of my appeal is, as I've not got one of these thingmys and never used one before, does anyone have a pattern/design/method for making this whatchamacallit????? Should I be able to open it !!!(could be a good opening for meeting beefy young hunks at the airport ...'Oh please could you help me with my ....' )I do have a thingy the strap goes through, @Sakar can explain what it is.
