Abstract: A male safety plug unit which fits a female unit to form a connection between contacts of the female unit. The male unit includes a body having sockets in end portions. A U-shaped connector member has arms which extend through bores which connect the sockets and includes a central portion exposed in a first one of the sockets. End portions of the arms are exposed in the second socket. An end cap is mounted in said first socket and engages the central portion of the U-shaped connector member to hold the U-shaped connector member in position. A chain socket in the end cap receives a chain link, a fastener extends through walls of the first socket and through walls of the chain socket to hold the chain link, the body, the end cap, and the U-shaped connector member in assembled relation.

Abstract: A cable connector assembly in which connector bodies carry spaced parallel cable contact members. Each cable contact member of one connector body is engageable with one of the cable contact members of the other connector body. A male ground contact is mounted in one of the connector bodies parallel to the cable contact members thereof and a female ground contact is mounted in the other cable connector body parallel to the cable contact members thereof. A latch in the connector body which has the female ground contact is movable transversely of the female ground contact and can engage in a slot in the male ground contact when the connector bodies are in assembled relation.

Abstract: An end fitting retainer for welding equipment which holds a cable end fitting on a connector stud. The retainer includes a nut for threadably engaging the stud. A housing rotatably supports the nut. Guard members in a socket in the housing surrounding the head end of the nut overlie the nut. An opening in the guard members permits a wrench to turn the nut but prevents entry of a finger. A flange on the nut engages flanges on the guard members to hold the guard members in the socket. Interconnecting means on the housing and on the nut retains the nut in the housing.
