Inter cooler pipe keeps popping off at top end (egr)

Wondered if anyone has a solution for the intercooler pipe popping off at the top end of the engine to the left.   Lugs are definitely worn but wondering if this could be fixed or a new pipe required.  Cable ties only slightly effective, but still get slight roaring noise and engine cutting back, as airnseems to be still getting in.   It's not the bottom of hose as I've read in various other posts on here near the headlight but the top end.
