ABSTRACT:
A combination of an engine block heater and electrical coupling includes the conventional cylindrical insert which slides into a sleeve on the mounting member for the block heater. An additional spring clip member is provided to hold the electrical coupling in place. The spring clip member has a collar surrounding a rib on the connector body and a pair of spring arms extending at right angles to the collar along a sleeve of the coupling to snap behind a rib on the sleeve. The spring clip arms are connected to the collar at an outer edge thereof with a pair of lobes of increased diameter between the spring clip arms for pushing of the collar longitudinally. A central opening of the collar engages over the connector body with a pair of inwardly projecting portions which slide along slots to a groove at the rib on the connector body.
