1. Medical implant (1) comprising:
a housing (2), and
a socket (20) arranged on the housing (2) for receiving an end portion (3) of a lead (30), the socket (20) having a strain relief (21) for the lead (30),
characterized in that
the strain relief forms a sleeve (21) which surrounds a through-opening (22) for receiving the end portion (3), wherein a seal (23) protrudes from an inner side (21a) of the sleeve (21) facing the through-opening (22), wherein the sleeve (23) is designed to sealably close the through-opening (22) when no end portion (3) of a lead (30) is inserted into the through-opening (22), and to sealingly abut against an end portion (3) of a lead (30) and thereby provide a strain relief for the lead (30) when the end portion (3) is inserted into the through-opening (22).
