A thermal sensor incorporating an improved retention clip is disclosed herein. The improved retention clip is both easily fabricated from either sheet stock or wire stock and is designed to be easily and securely assembled to the sensor housing and provides a convenient easy to use retention system for attaching the sensor to a tubular or generally cylindrical conduit member. The retention clip includes a gently angled lead-in portion which aids in guiding the clip into the conduit with little force coupled with a more sharply angled retention portion that substantially increases the force required to dislodge the sensor once assembled. Additionally, the clips are designed to minimize contact surface engagement with the conduit so as to minimize crevice corrosion. Portions of the clips may be covered with a suitable material to further limit the possibility of localized corrosion as well as to insulate the clip from the conduit member while also resisting relative movement therebetween. An optional protector disc is also disclosed which serves to provide increased protection against damage to the sensor body.

Temperature monitoring assembly having a thermostatic control with mounting clip

A spring clip is attached to a thermostat bottom wall for attaching the thermostat to tubing in heat exchange relationship. The spring clip has an opening that faces transversely of the thermostat longitudinal axis so that installation forces act in a direction that is more parallel to the bottom wall to avoid denting of the bottom wall. The spring clip has a flat mounting base attached to the thermostat bottom wall to spread forces over a large area of the bottom wall and to reinforce the bottom wall against deformation.

Thermostat with spring clip for accommodating out-of-round tubing

A packaging unit consisting of two molded plastic boxes, each having one side open. One of the boxes is laid flat with the open side up and receives therein a thermal cutoff/clip/resistor assembly. The other molded plastic box is placed over the first and the two are held together by symmetrical interlocking devices. The covers serve as assembly fixtures and protective housing.
