A tibial component of a knee prosthesis includes a tibial plate and a tibial insert, and anterior and posterior abutments projecting from an upper face of the tibial plate. The anterior abutment extends along at least part of the tibial plate and the posterior abutment extends for at least part of the tibial plate and comprises a part forming a promontory and an anterior cut-out, in particular central, in the form of a window formed in the anterior abutment opening onto the posterior face of the latter opposite the part forming the promontory. The tibial insert has a face upper, a face lower and a lateral face, which has a shape matching the part forming the promontory, characterised in that at least one flexible tab in the form of a hook projects centrally from an anterior face of the insert and locks by snap-fitting, into the anterior cut-out.
