1986 Pontiac Sunbird TBI wiring

Electrical problem
1986 Pontiac Sunbird 4 cyl Two Wheel Drive Automatic 147K miles

I am replacing the 1.8 L cyl head, and I am stuck with removing the red and blue wries that connect to the fuel injector.
There is a plastic clip that appears to hold them in place.

Can I pry this clip carefully and not break it?
Will the wires then release after I gently pry it open?

Thanks.
