The phrase "a physical tether" is correct and usable in written English.
It can be used to describe a tangible connection or link between two objects or entities, often in a metaphorical sense.
Example: "The astronaut felt a sense of security knowing there was a physical tether connecting him to the spacecraft."
Alternatives: "a tangible connection" or "a material link".
That asset might be gold or cash or even real estate; regardless of what it is, they create a physical tether to the real world.
Alternatively, it may function itself as a physical tether.
Such vesicles with a physical tether are categorized as 'tethered', and such vesicles with no obvious tether are categorized as the '30 nm pool'.
Tetherin is a transmembrane protein that forms a physical tether to prevent nascent HIV-1 virions from leaving the surface of infected cells (Neil et al., 2008).
ERMES is thought to function as a physical ER mitochondria tether that serves to distribute mitochondria (Boldogh et al., 2003) and to facilitate the exchange of lipids between the two organelles (Kornmann et al., 2009; Voss et al., 2012).
We propose that this dot RNA, probably via RNP proteins, contributes to the physical tether linking the GAL1 gene to the nuclear periphery.
The topology of tetherin dimers that form the physical tether is not entirely clear (Perez-Caballero et al., 2009), but the evidence that they can transduce a signal implies that at least some tetherin dimers must remain with their cytoplasmic tails in the cytoplasm.
Grp75 is a component of a trimeric complex IP3-Grp75-VDAC1 IP3-Grp75-VDAC1 IP3-Grp75-VDAC1ring of thatEregulatesochondria at MAMs (Betz et al. 2013), together with mitofusins 1 and 2 (Twig et al. 2008).
[Page C7.] All this will make it practically impossible, the skeptics insist, for anyone to build a profitable business in Wi-Fi, a short-range wireless radio technology that frees personal computers from their physical tethers to the Internet.

A disease mutation in RHD of RPGR1 19 or RPGRORF15 alone, or RID of RPGRIP1α1 alone, does not cause the subcellular uncoupling of RPGR from RPGRIP1α1 in COS7 cells, but each alone impairs partially the physical tethering of RPGR with RPGRIP1α1 and with the double mutations having a maximal effect in delocalizing subcellularly and untethering RPGR from RPGRIP1α1 in COS7 cells.
