ABSTRACT:
This disclosure depicts a novel frictional locking non-rotatable strain relief clamp for securing an electrical conductor which is attached to an electrical plug or socket and for relieving strain on the attachment of the conductor and plug or socket. The strain relief clamp comprises a first clamp section having front and back walls and a curved side wall. The back wall has a radially extending narrow slot centered in the first clamp section. A second clamp section also has front and back walls and a curved side wall. The back wall has a radially extending narrow slot centered in the second clamp section. A means for holding the first clamp section to the second clamp section is provided such that the back wall of the first clamp section aligns with the back wall of the second clamp section. The strain relief clamp further comprises a unitary adapter having two retaining means for slideably engaging the slots in the first and second clamp sections. The two retaining means are diametrically opposed on the unitary adapter. The unitary adapter also has an aperture for receiving the electrical conductor and means for fastening the adapter to the electrical plug or socket.
