The connector is of the type attached to one end of a first element and having a throat designed to allow engagement around a matching retaining collar mounted on a second element which is to be attached to the first element. The cross-section of the connector has an M-shaped profile having two central bars separated from side bars by empty spaces. The central bars delimit between them the throat and the side bars allow the connector to be attached to the elongated first element to which it is fitted. The present connection is particularly suited for erecting scaffolding.
