The device is equipped with the classical catheter (1) finishing in its front end in a tip (2) for attachment to the neck of the uterus, which is prolonged by a cannula (3) of smaller diameter. The device has said cannula (3) closed by means of an elongated lid (4'), with a rounded face, with a perimeter depression and concave curve (8) at the middle level, where orifices are established (5') as an outlet for the semen, specifically two orifices in diametric opposition, whose positioning is such that they are level with the uterine horns of the pig to be inseminated, by the introduction of the catheter (1), which is defined by a mark (11) in the cannula (3) or in a connector (12), which optimises the conditions of insemination allowing a lower semen consumption. In addition, the rear end of the lid (4') has a diameter after the cannula (3), to protect the edge of the free end from the latter, avoiding damage to the mucus of the female to be inseminated. In order to facilitate the process of application and to avoid contamination of the distal part of the cannula, this is presented divided into two portions that can be coupled together, the furthest away being introduced and therefore protected within the catheter (1).
