You know it happens! Your cables are not long enough and you have to connect two of them together to complete those last few centimeters.
If you want to secure the cable you are probably making a small knot where the cables connect to keep the cable connected if someone tugs it. If done wrong, this knot is stressing the weakest part of the cable – the plastic and metal parts, and it can be the end of your cable (and your shoot). This tip shows you how to both secure the cable against accidental tugging and keep your cable intact for future use.
The secret make a simple knot under the connection and this knot does not involve the weak part of the cable.
