The "c-bend" is a fast connection to get back into the action, easy to tie, and requires no splicing supplies. 

The knot is derived from the double sheet bend, a well known sailor's knot for bending a heaving line or any other two lines of dissimilar size.   The finished c-bend is a 9x sheet bend (but it can be tied with 12x or 14x wraps), with a four wrap unwind, modified to work with modern spectra, braid, nylon, or fluorocarbon.

The nip is spread out and multi-contact.  In an ideal c-bend knot, the working end's pull is transferred to the whole series of exterior wraps.  Those exterior wraps are buffered from any direct contact with monofilament by the inner wraps of the tag section, or so that's the theory of why this knot is better than others that put full pull spectra in direct contact with full pull monofilament.

Tying the knot, the final tuck back through the c-shaped bend in the mono gets the knot lined up for tightening.  But in the tied knot, the "tuck" is a series of 4 to 5 wraps buried inside the knot.  It doesn't matter if the tag end of the braid frays or passes back through the doubled mono because the knot stays tied.
