The present invention relates to a band-type wearable device for a pet that can easily attach or detach an electronic component-embedded case to/from a strap by one touch. The band-type wearable device for a pet according to the present invention comprises: a case having a coupling groove formed so as to open to the outside, and a locking groove concavely formed at an upper end of the coupling groove； a strap of which a distal end is connected to the case, and which is made of a flexible material wrapped around a pet's body and worn on the pet； a fixing bracket which is installed at the distal end of the strap, and includes a sliding coupling portion formed to protrude outwardly from the distal end of the strap so as to be inserted by sliding into the coupling groove and connect the distal end of the strap to the case； and a locking member having an inner end, an outer end and a locking protrusion, the inner end being coupled to the inner side of the distal end of the strap such that displacement occurs downward by means of a force pressing the upper side of the distal end of the strap, the outer end protruding outward from the distal end of the strap together with the sliding coupling portion so as to be inserted while sliding into the inner side of the coupling groove together with the sliding coupling portion, and the locking projection protruding from the locking member and being caught in the locking groove at the upper end of the outer end.La présente invention concerne un dispositif de type bande pouvant être porté par un animal de compagnie qui permet d'attacher aisément un boîtier à composant électronique intégré à une sangle ou de le détacher de la sangle par une simple pression. Le dispositif de type bande pouvant être porté par un animal de compagnie selon la présente invention comprend : un boîtier ayant une rainure d'accouplement formée de façon à s'ouvrir vers l'extérieur et une rainure de verrouillage formée de manière concave au niveau d'une extrémi
