Abstract: In a connector for the removable connection of an end of a neck strap to a pair of binoculars or similar optical device, to provide for a simple connection and disconnection with a reliable hold, the end of the strap has an attached clip incorporating two legs that can be elastically opened in a V-shape and that have inward facing holding projections on their insides, wherein a holding part with a lug is provided on the binoculars, said lug incorporating snap-in projections that extend laterally toward the outside in a manner so that the legs can be snapped onto the lug in such a way that their holding projections encompass the snap-in projections of the lug, and wherein a retention sleeve is provided, the free interior cross-section of which is dimensioned such that it can be slipped over the legs when they are in their snapped-on position, thus preventing the legs from opening.
