The end of an electric cable for energizing the motor of a submergible pump is attached to a motor head by a device comprising a rigid shell having a body of elastomeric material filling an end portion of the shell and projecting therefrom to form an insert. Conductors of the cable extend through the elastomeric material and have terminals that engage corresponding terminals within the motor housing. The body of elastomeric material is sealed in the shell, and the conductors are sealed in the body. The remainder of the shell is filled with strain relief material. The insert is tapered and has circumferential flexible ridges that engage and seal upon the cylindrical wall of a bore leading into the motor head. An integral circumferential bead on the body seals against the end of the shell and against a portion of the motor head surrounding an end of the bore.
