Abstract
A device for attaching parts of a spectacles frame to one another includes a first attachment element connectable to a first component part of the frame to be plugged into a second attachment element connectable to a second component part of the frame. A locking pin is active between the first and the second attachment element, in a removable manner, transverse to the plugging direction, so as to attach the first and the second component parts of the frame to one another. The first attachment element includes a pair of limbs constructed equidirectionally and at a distance from a common base, while the second attachment element includes a seat that can hold the pair of limbs in the axial plugging direction between opposing internal walls of the seat, the seat being intersected transverse to the plugging direction by an opening in which the locking pin is rotatably held.
