For the record, the operation of Ottolock is similar to a ziptie. The latter can be released by pushing a thin screwdriver blade from the outer side of the locking piece. In principle one might try a similar action with Ottolock. I tried it with mine, using different items as blades, but failed to push any blade in. However there might be someone with more skill and/or better utensils who might succeed, even for sports. A sign would likely be damaged ribs around the end of the strap from the original position of the locking piece on.
