A handle for a medical instrument having a handle housing that can be closed by a cover and having at least one drainage or irrigation hose in the handle housing that can be connected to a hose connection support. To create a handle that is of a simple construction and ensures a reliable fluid-proof insulated connection of the at least one hose and the hose connection support while protecting a material of the at least one hose, it is proposed that each drainage or irrigation hose should be connectable by an adaptor to the hose connection support and that the adaptor upon closing the handle housing can be pressed against the hose connection support by a stop positioned on the cover or on a base portion of the handle housing.
