As part of Orbital Surplus' replica line:

We are happy to offer a very accurate, high quality, replica S-1035 / S-1034 / ACES (Advanced Crew Escape System) wrist disconnects or wrist rings. (See last photo above, of real ACES glove disconnect)

The real reals are nearly impossible to obtain, and this style of ring has been used on a number of different high altitude pressure suits.

These were molded directly from high quality aluminum replicas, that are nearly identical to the real disconnect. 
The 2 piece disconnects are cast in a tough polyurethane plastic and have 2 sliding locks(yellow tabs) that lock the rotation of the mating rings. The clamp rings were machined from ABS.

Note: The real rings do have mirrored left & right versions, this set is two of the same side.
 
Produced by our partner, Global Effects Inc., this style of disconnects have been used on some of their highest quality space suit replicas. 

Each Set Includes:
2 - Blue - Glove side
2 - Blue - Suit side
4 - Clamp rings


Here at Orbital Surplus, we collect odds and ends from anywhere in the galaxy. So depending on what empire has collapsed, space freighter has crashed or Transport "got lost", we never know what we will receive next. However, we have lost our lease on the asteroid we have called home for more than 30 solar cycles and have to move. So we are finding stuff we forgot we had, and this is where you luck out, cause it all has to go!
