Fixing suitable for corrugated conduit inside a chased masonary wall and suitable clips?
The 2017 NEC article 362.10.1.B allows flexible non metallic conduit (smurf tube) concealed in walls floors and ceilings.
362.30.A securely fastened every 3 feet. 
Zip tie anchors are even allowed code added a statement that the zip tie had to be listed for securing and supporting (my state deletes this because this is what a zip tie is for). I usually purchase a bag of plastic clamps that are held in with a nail or screws if 1 hole at the start and end of a run I will use 2 one on each side so when fishing the wire through it it won’t pull lose from the clamps and on the inside radius of any unsupported turn when the wires pull tight if the clamp is on the outside it can pull out on occasion if the wall is closed you may not even notice it.
