Abstract: Combination of a locking lever and a connector of the type utilizing a female housing member and a male housing member, wherein one of the male and female housing members includes studs arranged on two opposite walls, and wherein the locking lever is a U-shaped member that has two flanges and a holding strip portion. The U-shaped member is mounted in an articulated manner on two corresponding walls of another of the male and female housing members. Each of the two flanges has a cam adapted to cooperate with one of the studs. The locking lever is movable at least between a rest position and a locking position. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Abstract: An electrical connector housing element has a locking key inserted in a passage parallel to and between channels in the housing element. The housing element has elastic tongues projecting into the conduit and the locking key terminates in a protuberance which, in a locking position, pushes the tongues through corresponding slots into the channels so that they project into the channels at the rear end of the electrical contact members.

Abstract: An electrical connector comprises a male member with conduits arranged in rows and in transverse lines and each designed to receive an electrical contact member. The electrical contact members are locked by a locking key mobile in the male member perpendicularly to the conduits and having slots corresponding to the rows. The key includes notches in the slots and disposed along the transverse lines. The male member and the key carry markers corresponding to the rows and to the transverse lines.
