What holds a jet engine to the wing?

Engines are attached to a pylon

The podded engine is not attached directly to the wing but to a pylon. … The pylon is fixed into the wing structure, with a solid and very secure fitting. The pylon creates some distance between the engine and the wing.

What is engine pylon?

A pylon connects the engine to the airframe of an aircraft. This design uses air passing through the pylon to actively disrupt the jet engine exhaust stream after it exits the engine, disrupting and redistributing the axial and azimuthal distributed sources of jet noise from the aircraft.
