A catheter designed to be anchored in an internal cavity of a patient such as a drainage catheter employs a novel hub design. The hub has a slide member slidably coupled to the hub and a latch that latches the hub and the slide member together when the slide member slidably moves relative to the hub. Preferably, latching takes place when the slide member moves relative to the hub in an axial direction of the hub. A manually operable release member is provided on the hub such that the latch is disabled from unlatching unless the release member is manually operated. This feature advantageously limits a person's ability to accidentally unlatch the hub.
