Systems, devices and methods for pipe connectors and associated components are disclosed. Features for no hub clamps, for locking mechanisms on no hub clamps, for tools for no hub clamps, and for gaskets are described. The clamp has a band with a locking mechanism for convenient locking together of the ends of the band about two adjacent pipes. The locking mechanism may include a securement feature such as a tab on one end of the band and a complementary engagement area on the other end. The band may have arcuate gripping projections whereby rotation of a tool head causes linear translation of the two ends of the band. The various locking mechanisms may be tightened and secured using various tools having engagement features complementary to the gripping projections. The gaskets may be hourglass-shaped to facilitate assembly onto pipe ends with longitudinal membrane sections that collapse when a clamp is secured over the gasket.
