A device for releasably and adjustably securing a medical tube includes a receiver and a tail, which may be used for thoracostomy. The receiver has a receiver aperture and receiver teeth. The tail has center holes along a central axis of the device. Raised tail teeth are formed on the tail between the central axis and the tail sides. The tail teeth are arranged to engage the receiver teeth when an end of the tail is fed through the receiver aperture to form a tail loop. The receiver teeth define receiver teeth apertures that are smaller than the receiver aperture. The tail loop is adjustable to tighten around the medical tube.
