Problem applying subsurf modifier

Hi im trying to model a lamp, everything is ok, except when i apply the subsurf modifier the “gripper” of the lamp do some weird stuff.

I set the mean crease to 1 in everything and still its showing that “glitch” i dont know how to call it :confused:

Whitout subsurf:


Get rid of the ngons (faces with >4 edges)
Quads + subsurf = good
Tris or ngons + subsurf = weird results


Wow, I thought just the tris give weird results, thank you so much you are awesome :smiley:
