Abstract
A safety pin comprised of a pin having one end pivoted to a pivot bearing at one end of an elongated base plate above a face board, and a pointed opposite end releasably retained to a pin holder at an opposite end of said elongated base plate, wherein said pin holder comprises two side springs for holding the point of said pin, and a front guard for protecting the point of said pin, said side springs having L-shaped pawls releasably retained together for locking up the point of said pin. Squeezing said two side springs inwards causes said L-shaped pawls to move apart for passing the point of said pin; releasing the pressure from said two side springs causes said L-shaped pawls to retain together in locking up the point of said pin.
