Abstract
A removable protection device is for a transmission seal providing tightness between a differential housing and a transmission shaft inserted therein during installation. The removable protection device includes a cylindrical, longitudinally slotted protection ring which is placed under the seal so as to protect same during the insertion of the shaft, a bearing flange for bearing on the housing, connected to the ring and having a radial opening following the slot of the ring, a removal handle attached to the bearing flange, and an abutment projecting axially towards the outside of the housing from the annular flange, so as to halt the insertion of the shaft in a reference position.
