A drainage catheter hub for use in connection with a drainage catheter to receive and secure a suture therein, wherein the hub includes: (i) a housing having a channel to accommodate the suture therein; (ii) a bistable locking mechanism positioned in the housing and being adapted to provide selective securement of the suture; and (iii) a resilient outer layer utilized in connection with the bistable locking mechanism and coupled to the housing. The bistable locking mechanism is configured to: (i) allow movement of the suture when the bistable locking mechanism is in a first position; and (ii) minimize axial movement of the suture when the bistable locking mechanism is in a second position. The resilient outer layer is adapted to allow a user to actuate the bistable locking mechanism between the first and second positions to selectively secure and release the suture.
