The patent relates to a device whereby an apparatus securely interconnects a line or an instrumentation package to a rigid surface underwater. A suction cup member has a lip which pliably accommodates the surface and allows a trigger mechanism to be brought in contact with the surface. The trigger mechanism releases a coiled helical biasing spring which distends an essentially cylindrically shaped bellows to create a multiplied suction or a vacuum inside the suction cup. The multiplied suction holds the apparatus and instrumentation package or line securely on the surface. Because of its straightforward design and uncomplicated mode of operation, it is fully capable of being deployed by marine mammals. Having the suction cup and bellows integrally molded reduces the possibility of leaking and enhances reliability.
