Releasably attachable clip

Claim 1

A clip adapted for releasable attachment to an article to be monitored by a monitor, said clip comprising; a body adapted for encapsulating receipt of a monitor activating device, said body comprising two complementary molded sections; and a molded, one-piece slide member slidably engageable with said body, said slide member having a first position relative to said body for release of said article and a second position relative to said body for releasable attachment to said article, said body and slide member defining a plurality of releasable spring-locking members and matching spring-locking member catches to releasably lock said slide member in said second position, said releasable spring members formed as integral parts of said body and said catches defined by the ends of said passageways formed in said slide member, said locking members and locking member catches being interior of said clip when said slide member is in the second position and accessible from the exterior of said clip only via passageways, one for each mating locking member and catch, opening to the exterior of said clip, said slide member releasable from said second position only upon simultaneous, axial mechanical contact of all of said spring-locking members, said passageways being substantially parallel to the slide axis of said slide member, at least two of said catches being located at substantially different axial distances from the exterior openiNg of said passageways to make application of the required simultaneous coaxial mechanical contact difficult without the use of a specially configured, complementary multi-pronged tool, said body and said slide member define a pin and a pin receiving cavity, said pin received in said cavity when said slide member is in said second position.
