straplings

"Straplings" are the tiny bits of wire insulation that remain as scrap after stripping the ends of electrical wiring in preparation for crimping or soldering on terminals. This is most precisely used to refer to the circular "rings" of insulation pieces removed in one piece during the stripping process.
Singular form is "strapling".

It is customary and considerate to vacuum up the straplings after completing a harness rework in the Elab.
