Claim:
An electrical connector comprising: a housing; a mat seal connected to the housing, the mat seal comprising a plurality of cavities; a rear grid connected to the housing, the rear grid comprising a plurality of passageways; and at least one thermoplastic plug located in one of the cavities of the mat seal, where the thermoplastic plug is a single one-piece member, wherein the thermoplastic plug comprises a front part and a rear part, wherein the front part creates a seal with the mat seal, and wherein the rear part defines a zone holding the thermoplastic plug in one of the passageways of the rear grid, where the rear part is at least partially hollow, where the rear part is elastically deformed inward into the hollow by the rear grid, where the elastic deformation of the rear part into the hollow results in the rear part exerting an outward holding force against the rear grid in the passageway.
