Broken transformer T4 TCM1-63AX+ (RX1-H)

Hello Guys, After struggling with the coax connecters i see that the top from the transformer T4 TCM1-63AX+ (RX1-H) is broke off. It looks like this small plate itself is not broken. Maybe i can just glue it again. Is this possible and what glue shall i use? Regards Ben [RF-1024x368]
