Abstract: The invention relates to an electrical connector including a housing for electrical contacts having a plugging face and a front grid to be mounted onto the plugging face of the housing according to a plugging axis, the housing including a series of locking members that lock the contacts in place, the front grid including mounting arrangements arranged for allowing the mounting of the front grid onto the housing from a closed position into a closed position only if the contacts are locked in place in the housing, and at least one retractable stop member arranged for stopping the plugging of the counterpart connector with the connector as long as the front grid is not in the closed position, wherein the or each retractable stop member is arranged such that its retraction in the closed position of the front grid can be caused by a sole force exerted thereon in a direction substantially parallel to the plugging axis.
