Narrative:

I was sent to aircraft X to clear an MEL on the missing life vest seal. (I) found a zip tie on the pouch that prevented the life vest from being used. I removed the zip tie; inspected the life vest; installed the proper seal and cleared the MEL. I then asked the flight attendant 'how it got the zip tie on there?' (I) was told by him that the operations supervisor in (sta) had installed the zip tie. (I) also asked the captain (and) he was not aware of the zip tie being there.
