A valve device includes male and female housings having, respectively, exterior and interior annular channels. The male housing is receivable into the female housing such that the exterior and interior annular channels together define a toroidal tube. The male and female housings together define a fluid through-passage. There are first and second valve elements disposed, respectively, in the male and female housings. Ball locks are receivable into the toroidal tube. The ball locks axially lock the male and female housings together but permit rotation between the male and female housings. A lock includes first and second pin holes in, respectively, the male and female housings. The lock is engageable to rotationally lock the male and female housings when the first and second pin holes are in alignment.

A connector system for a medical device includes a first connector having an elongate opening, and a second connector including a lock portion, where the first connector is movable relative to the second connector between an initial position where the first connector is not in fluid communication with the second connector and an activated position where the first connector is in fluid communication with the second connector. The system also includes a locking member connected to the first connector. The locking member is transitionable between an unlocked position where the second connector is movable within the elongate opening of the first connector and a locked position where the locking member is configured to engage the lock portion of the second connector to lock the first connector to the second connector in the activated position. The locking member comprises a spring body received by the elongate opening of the first connector.

Pipe joint connector (10) comprising a flexible elongate portion (12), wherein the flexible elongate portion is provided with a plurality of rotatable members (14).

A plug connector includes a housing, a locking element and a verification element. The housing has a receiving chamber, a connection piece and a duct through which fluid can flow. The locking element is movable between an open position and a fastening position, a plug can be inserted in the receiving chamber in the open position of the locking element, and a plug inserted in the receiving chamber can be fastened within the receiving chamber via the locking element in the fastening position of the locking element. In an open position of the locking element, the verification element is at least partially covered by the locking element, and in a fastening position of the locking element, the verification element can be read.
