A carriage for housing an ink cartridge as a source of supply of ink to an ink-jet printhead for an ink-jet printer comprises a snap hook for locking engagement with a lock lever that is pivotally supported by a case. The hook includes a cantilever fixed at one end to a sidewall of the case and a head for engagement with the lock lever. The cantilever is elastically inclined by said lock lever and allowed to snap back toward its unstressed state to put the head into a window of the lock lever into frictional engagement with a predetermined surface of a knob of the lock lever. For releasing this engagement, manually pressing the cantilever to incline the cantilever causes the head to move the knob until the window comes into registry with the head.
