Bra shoulder strap adjusters fix

A washing machin has teared my wife bra shoulder strap. Both ring and "eight" were destroyed. The fix was needed - infant feeding bra.
Open designs were made to avoid ripping and sawing strap loops - stitches with high load and complicated pattern.
"Eight" must be placed in such orientation that strap end tension will lock cut wedge in the middle bar. Grue might be needed to lock open ring after assembly onto a strap.
