These snakes, to my knowledge, have no fangs. They are also non-venemous (if that wasn't apparent). They are not a constrictor species either
.
The way they defend themselves is [as seen in the video] by rubbing their scales against one another to produce the sound heard in the video, which is a mimicry of the MUCH deadlier saw-scaled viper

For comparison you can see a saw-scaled viper's display here:
