Abstract: Plastic covered equipment is secured to a support surface such as a table or the like by first and second interconnected coupling devices. The first coupling device is mounted on the support surface, while the second coupling device is embedded into the plastic covered equipment. The second coupling device includes a body member having a stub shaft secured to the first end thereof which terminates in a pointed probe head having an inner face with a greater diameter than that of the stub shaft. A concave surface on the first end of the body member surrounds the stub shaft and terminates in an arcuate annular shoulder on the first end of the body member. The annular shoulder has a diameter greater than that of the probe head and creates an annular space with respect to the inner face of the probe head.
