Abstract: A clamp for connecting together two parallel elongate members has a pair of body parts with respective recesses that can be brought together to define a through-opening receiving one of the members. To one side of the through-opening each body part has spaced tubular portions with coaxial bores. The tubular portions of the body parts can be meshed together to align their bores and the other of the elongate members inserted through the bores to lock the body parts together axially but allowing them to pivot on the further member. To the opposite side of the through-opening the body parts have snap-fastening recesses that engage a clamping lever. Cam mechanisms between the clamping lever and the body parts allow the body parts to be flexed together by pivoting the lever, so gripping both elongate members and locking them together releasably.
