Snap fit accessory for heat trace cable

A kit or assembly comprises a plug body, a housing, and an end cap. The plug body comprises an opening sized to receive a cable, and first and second members. The first member is pivotably connected to the plug at a first position and comprises a first blade extending inwardly relative to the plug body and a first electrical contact. The second member is pivotably connected to the plug at a second position and comprises a second blade extending inwardly relative to the plug body and a second electrical contact, where the second position is longitudinally offset from the first position. The housing comprises a socket to receive the first electrical contact and the second electrical contact and the end cap is threadably engageable with the housing, with the end cap comprising an interior sized to receive the plug body. Engaging the end cap with the housing causes the first member and the second member to contact the housing and pivot inwardly such that the first blade and the second blade pierce a jacket of the cable positioned within the plug body to contact the first and second electrical wires of the cable respectively, establishing an electrical path from the first and second wires of the cable through the first electrical contact and the second electrical contact to the socket.
