Zipper lock to lock shoes or dresses- add to an exsiting zip

Made for locking zips of boots, dresses, underwear… anything what is closed by a standard size zip. Can be added later to almost every garment, your slave is not allowed to take off.

Most standard zipper can be altered: two tiny holes have to punctured through the polyester tape of the zip, through which you can thread in the lock shackle and block the zipper slider in its closed position.

Ziplock closure of a Zip with the Z-lock


  • zipper width not larger than 8 mm  (teeth without textile stripe)
  • zipper’s tape accessible at both sides of zipper in a distance of ca. 13 mm

The Z-lock is a small security lock with a removable, specially bent hasp. The lock can be added to any existing zipper, which meets the conditions mentioned above.

It has a good fit to the zipper, and will not stand out. The lock is rounded, so no damage to the shoes or clothes will happen. The hasp has a tight fit to the zipper and can’t be felt inside.

The shoes or clothes can be worn also without a lock after modification; the tiny holes are almost invisible.

Possible application: shoes, clothes, bags, etc.

 How to mount the lock on a clinging zipper of tight fitting dress or shoe

Manual for modification of a existing zipper to mount a Z-lock

The zipper’s slider is in its top upper position. The slider’s pull tab is turned downward.

At the end of the tab make a mark onto the zipper’s tape left and right of the zipper closure, symmetrically. Pull away the overlapping borders of leather or textile. Control the position by placing the lock’s shackle for a trial. The overlapping borders must not be perforated!

Heat the included pin at its tip only, whilst keeping it at the other end, with a gas flame (best method). The pin will not get hot at the grip’s end in a while. If it’s becoming to hot, cool it in a glass of water and start again.

If the tip of the pin is hot enough, burn a hole at the marked position at either side of the zipper through the polyester tape. Burning the holes instead of punching has the advantage, that the holes will not fray. You may also punch the holes if you prefer.

Be careful with light coloured zipper tapes! Make a test hole first inside in the tape, which is not seen.
