The invention relates to a supply connector (10) for a discharge lamp (12) of the type which comprises an insulating housing (18) in which an opening (56) is provided for the axial introduction of a free end (26) of the glass body (28) of the discharge lamp (12) comprising a longitudinal electrode (30) formed by a front section (32) which extends to the exterior of the body (28) and a rear section (34) which extends inside a front section (36) of the free end of the body (28) and which is designed to be supplied with a direct current, and of the type in which a contact blade (20) is formed, which blade cooperates with the front section (32) of the electrode (30) for connecting the lamp (12) to an electrical supply member, characterized in that it comprises an electrically conducting ring (22) which is connected to ground, which is axially traversed by the front section (36) of the free end of the glass body (28), and which is designed to be at least partly in contact with a portion (150) of the outer wall of the glass body (28) of the discharge lamp (12) so as to facilitate the ignition of the latter.

A supply connector (10) as claimed in the preceding claim, characterized in that the ring (22) is elastically deformed upon the axial introduction of the front section (36) of the free end of body (28) of the lamp (12) body so as to clamp around said portion (150) of the outer wall of the body (28).
A supply connector (10) as claimed in the preceding claim, characterized in that the rear part (16) comprises an accommodation space (78) for positioning and mounting the contact blade (20).
A supply connector (10) as claimed in the preceding claim, characterized in that the insulating wall (102) extends axially away from the front bottom portion (124) of the front part (14), and the ring (22) is axially retained by the rear free end (138) of the insulating wall (102) and the transverse rear bottom portion of the rear part (16).
A supply connector (10) as claimed in any one of the preceding claims, characterized in that the contact blade (20) is formed as an elastic clip which locks in the front section (32) of the electrode (30) and which cooperates with mating retention means (38, 154) of the electrode (30) so as to define the axial position of the lamp (12) with respect to the housing (18), in particular the axial position of the free rear end (160) of the rear section (34) of the electrode (30) with respect to the ring (22).
A supply connector (10) as claimed in any one of the preceding claims, characterized in that it comprises a flexible sealing element (24) for the inlet opening (56), connected to the exterior of the housing (18).
