Using a cotter pin to secure a cotter pin. Interesting concept.
Here is a dictionary definition:
A cotter is a pin or wedge passing through a hole to fix parts tightly together. In English usage cotter pin has the same meaning.
Typical applications are in fixing a crank to its crankshaft, as in a bicycle, or a piston rod to a crosshead, as in a steam engine. Note: the angle of the wedge determines the position of the parts being held, therefore on a bicycle the pedal arms will only be at 180 degrees to each other if the angle of the cotter pin's wedge is the same on both pins.
cotter (n.)
"wedge-shaped piece or bolt which fits into a hole used in fastening or tightening," 1640s, of uncertain origin; perhaps a shortened form of cotterel, a dialectal word for "cotter pin or bolt, bracket to hang a pot over a fire" (1560s), itself of uncertain origin. Cotter-pin is attested by 1849.
And another:
NOUN
1. any part, such as a pin, wedge, key, etc, that is used to secure two other parts so that relative motion between them is prevented
2. short for cotter pin
VERB
3. (transitive)
to secure (two parts) with a cotter
