A positioning apparatus for restraining an object includes a base plate, an attachment plate, and a securing element. The base plate may include guides into which protrusions of the attachment plate slide to alter the positioning apparatus from an open position to a closed position. The base plate also includes receivers to receive tubular members, which have their movement restrained by the receivers and the securing elements in the closed position. The positioning apparatus may also include a latch to help maintain the closed position during operation.
