This is Vav ו and Yod י, which is in the mystery of the letter Zayin ז, through which all ‘crownlets’ (tagin) are called.
(Ex. 28:7)... two shoulder pieces adjoining, – this is ‘the higher shoulder’ and ‘the lower shoulder’, which are right and left, and they are Hei-Hei ה־ה,... to its two edges... – these are Vav-Vav ו־ו, and with them Hei-Hei ה־ה is joined. And because of this:... to its two ends, and it is joined.
