did you sneeze on your master link?silicone on the clip is crap,keep it clean,if you look close the clip is stamped out,it has a sharp and dull side(bit like some #$%*s around here?)fit it so the sharp edge is facing outwards,that way it has less chance of slipping over the grooves in the pins,its more likely to catch and bite on them as opposed to having the smooth curved edge resting or being pressured against them,not dead important but just gives you that "edge"of safety.
