Hi,
In your pic, the hose connector is the faulty part. Take a look at the pics below. Note that the connector has the retainer portion still connected to it. The connector portion on yours is broken and still on the air filter box. In this case, the hose needs replaced or if you want to try, you can find a short piece of steel pipe or even PCV that fits snuggly into the pipe. As long as the pipe you find is strong, you can push it into the air box opening and use a clamp to seal it at the hose and at the box. Or go to a salvage yard, cut that section off a vehicle, and splice it to the hose portion on your vehicle. If you do find a good used one, take the entire assembly.
Other than that, you will need to purchase the secondary air injection inlet hose which is an assembly. The OEM part number is 22759748. If you google search GM part number 22759748, you will find the new assembly. What you will also find is the part is discontinued. You may get lucky by checking places like Ebay or Amazon.
Note: The pics I attached are general pics just so you can see the design. However, they should be the same as you have or extremely similar. Pic 3 shows the actual part.
Let me know your thoughts or if you have other questions.
Take care,
Joe
