A carrier for a wrist instrument when it is removed from the wrist band comprises a case made in two pieces of identical construction which slide together and house the wrist instrument and its attachments. The two carrier sections each have a tongue extending across a parting line which is received in a mating channel on the other carrier section. Additional guide pins and recesses hold the assembly in alignment. A holster for the assembled carrier sections cradles the assembly securely and includes a belt clip for attaching the holster to a belt.
A lanyard, tether or leash is secured to a PERSONAL DIGITAL ASSISTANT device (PDA) by a tether latch receiving and positively latching onto a "plug-in" or docking base of typical PDA. The body of the tether latch defines a socket with a mating curvilinear circumferential lip for snugly receiving the PDA docking base with a stationary catch nib being received in a latch notch on one side of the PDA docking base. A toggle coupled to the latch body manually translates carrying a catch nib into and out of the corresponding latch notch on the opposite side of the PDA docking base. A spring compressed between the latch housing and the toggle positively biases the latch `normally latched.` A tether, lanyard, leash strap or cord is fastened between a tether hole through a tab on the latch body and the neck, the wrist; belt or clothing of a user to prevent the PDA from striking ground when fumbled or inadvertently dropped by the user.
